Hello I have a Centos 5: Linux xxx.xxx.xxx 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux Problems: - When I connect with SSH, each command take until 2 min to run! - Restart the server takes 16 minutes on average. - I have a web page in this server (PHP (Joomla) with Apache/2.2.8 (Unix) ) and each page takes 1 min in load. - I assumed it was because originally it was connected with IPv6, because when running the command "lsmod | grep v6" showed me the following: ipv6 261473 125 xfrm_nalgo 13381 1 ipv6 But using this website (http://techno.mayix.net/deshabilitar-ipv6-en-redhatcentos/), I disable IPv6 connection because when running the command "lsmod | grep v6" showed me nothing. But the problems of slowness, still. - When I run the command top give me this: Code: top - 09:40:08 up 10 min, 1 user, load average: 18.89, 14.99, 8.02 Tasks: 153 total, 13 running, 140 sleeping, 0 stopped, 0 zombie Cpu(s): 57.1%us, 42.4%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.2%hi, 0.3%si, 0.0%st Mem: 1555380k total, 667200k used, 888180k free, 18332k buffers Swap: 2048276k total, 0k used, 2048276k free, 193784k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2265 mysql 15 0 133m 23m 6052 S 35.8 1.5 2:43.58 mysqld 2868 apache 15 0 42092 21m 4520 S 18.2 1.4 0:19.51 httpd 3112 apache 16 0 41844 21m 4536 S 18.2 1.4 0:09.18 httpd 2506 apache 15 0 42108 21m 4516 S 17.9 1.4 0:23.15 httpd 3471 apache 16 0 41732 20m 4252 S 17.9 1.4 0:02.59 httpd 2567 apache 15 0 42060 21m 4496 S 16.9 1.4 0:20.84 httpd 2625 apache 16 0 41840 21m 4568 R 16.9 1.4 0:16.53 httpd 3461 apache 15 0 41460 20m 4260 S 16.6 1.4 0:02.17 httpd 2593 apache 15 0 42084 21m 4480 S 16.3 1.4 0:15.37 httpd 2429 apache 15 0 42040 21m 4484 S 9.8 1.4 0:14.31 httpd 3477 apache 18 0 36900 15m 3792 R 5.5 1.0 0:01.24 httpd 3499 apache 19 0 37432 16m 3840 R 3.3 1.1 0:01.40 httpd 2417 apache 15 0 40544 20m 4508 S 1.3 1.3 0:18.89 httpd 3520 root 15 0 2420 1060 800 R 1.3 0.1 0:00.46 top 3464 apache 15 0 41332 20m 4432 S 0.7 1.4 0:04.03 httpd 2423 operador 15 0 10032 1596 1024 S 0.3 0.1 0:00.54 sshd 2463 root 16 0 2052 636 556 S 0.3 0.0 0:01.84 hald-addon-stor 2482 apache 15 0 37224 16m 4508 S 0.3 1.1 0:17.95 httpd 1 root 15 0 2152 672 580 S 0.0 0.0 0:02.09 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.10 migration/0 3 root 34 19 0 0 0 R 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.05 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/1 7 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root 10 -5 0 0 0 S 0.0 0.0 0:00.06 events/0 9 root 10 -5 0 0 0 S 0.0 0.0 0:00.04 events/1 10 root 10 -5 0 0 0 S 0.0 0.0 0:00.03 khelper 11 root 14 -5 0 0 0 S 0.0 0.0 0:00.02 kthread 15 root 10 -5 0 0 0 S 0.0 0.0 0:00.08 kblockd/0 16 root 10 -5 0 0 0 S 0.0 0.0 0:00.05 kblockd/1 17 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 kacpid 74 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 cqueue/0 75 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 cqueue/1 78 root 15 -5 0 0 0 S 0.0 0.0 0:00.00 khubd 80 root 14 -5 0 0 0 S 0.0 0.0 0:00.03 kseriod 146 root 19 0 0 0 0 S 0.0 0.0 0:00.00 pdflush 147 root 15 0 0 0 0 S 0.0 0.0 0:00.50 pdflush 148 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 kswapd0 149 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 aio/0 150 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 aio/1 305 root 11 -5 0 0 0 S 0.0 0.0 0:00.00 kpsmoused 349 root 10 -5 0 0 0 S 0.0 0.0 0:00.00 mpt_poll_0 350 root 12 -5 0 0 0 S 0.0 0.0 0:00.00 scsi_eh_0 354 root 12 -5 0 0 0 S 0.0 0.0 0:00.00 ata/0 355 root 12 -5 0 0 0 S 0.0 0.0 0:00.00 ata/1 356 root 12 -5 0 0 0 S 0.0 0.0 0:00.00 ata_aux 363 root 13 -5 0 0 0 S 0.0 0.0 0:00.00 kstriped 376 root 13 -5 0 0 0 S 0.0 0.0 0:00.00 ksnapd Why is this server so slow? What could be happening? Why Apache appear to have many instances created? And why always consumes so much CPU? P.D.: Sorry for my english
Those Apache children are serving up webpages..otherwise they would not show at the top of your output while running "Top" Have you checked your access and error logs to see if there's any suspicious activity? What hardware is in this box? It seems to be overloaded and IMO should not be even with that level of activity. If you notice, the percent of CPU usage adds up to quite a bit more than 100%

I would guess that one of three things are happening: Your hardware has a major problem Your software is improperly configured Your server is under some sort of attack Have you checked the following for clues? /var/log/messages /var/log/secure /var/log/httpd/ (both access and error logs in there)

Initially I assumed it was a real machine, but then appears to be a "VMWare" but do not yet know the version.
Ok.... Mmmm. This is so weird. I just conect with my server by SSH and now it's fast! It is possible that a requirement to note the speed of the server after changing the settings by disabling the "IPv6" is restarting the client? Because that's all I've done and now the site loads fast and the connection via SSH is fast too! Now "top" showed me this: Code: top - 10:58:14 up 2 days, 9:10, 1 user, load average: 0.56, 1.04, 0.64 Tasks: 124 total, 2 running, 121 sleeping, 0 stopped, 1 zombie Cpu(s): 0.3%us, 0.7%sy, 0.0%ni, 99.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1555380k total, 1460660k used, 94720k free, 60656k buffers Swap: 2048276k total, 80k used, 2048196k free, 1114088k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4299 apache 15 0 0 0 0 Z 0.7 0.0 0:01.09 httpd <defunct> 4513 apache 15 0 38092 17m 4452 S 0.3 1.2 0:01.27 httpd 4646 root 15 0 2412 1040 800 R 0.3 0.1 0:00.45 top 1 root 15 0 2152 640 552 S 0.0 0.0 0:01.24 init 2 root RT -5 0 0 0 S 0.0 0.0 0:01.49 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.78 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/1 7 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root 10 -5 0 0 0 S 0.0 0.0 0:00.32 events/0 9 root 10 -5 0 0 0 S 0.0 0.0 0:00.15 events/1 10 root 10 -5 0 0 0 S 0.0 0.0 0:00.25 khelper 11 root 10 -5 0 0 0 S 0.0 0.0 0:00.00 kthread 15 root 19 -5 0 0 0 S 0.0 0.0 0:01.12 kblockd/0 16 root 10 -5 0 0 0 S 0.0 0.0 0:00.67 kblockd/1 17 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 kacpid 74 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 cqueue/0 75 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 cqueue/1 78 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 khubd 80 root 18 -5 0 0 0 S 0.0 0.0 0:00.00 kseriod 146 root 15 0 0 0 0 S 0.0 0.0 0:02.54 pdflush 147 root 15 0 0 0 0 S 0.0 0.0 0:15.59 pdflush 148 root 10 -5 0 0 0 S 0.0 0.0 0:03.60 kswapd0 149 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 aio/0 150 root 14 -5 0 0 0 S 0.0 0.0 0:00.00 aio/1 304 root 11 -5 0 0 0 S 0.0 0.0 0:00.00 kpsmoused 349 root 10 -5 0 0 0 S 0.0 0.0 0:00.01 mpt_poll_0 350 root 16 -5 0 0 0 S 0.0 0.0 0:00.00 scsi_eh_0 354 root 16 -5 0 0 0 S 0.0 0.0 0:00.00 ata/0 355 root 16 -5 0 0 0 S 0.0 0.0 0:00.00 ata/1 356 root 16 -5 0 0 0 S 0.0 0.0 0:00.00 ata_aux 363 root 18 -5 0 0 0 S 0.0 0.0 0:00.00 kstriped 376 root 19 -5 0 0 0 S 0.0 0.0 0:00.00 ksnapd 387 root 20 0 10032 2752 2204 S 0.0 0.2 0:00.03 sshd 389 root 10 -5 0 0 0 S 0.0 0.0 0:04.76 kjournald 394 operador 15 0 10032 1596 1024 S 0.0 0.1 0:00.04 sshd 397 operador 16 0 4620 1368 1156 S 0.0 0.1 0:00.04 bash 414 root 10 -5 0 0 0 S 0.0 0.0 0:00.34 kauditd And "df -h" showed me this: Code: Filesystem Size Used Avail Use% Mounted on /dev/sda3 5.8G 2.2G 3.4G 39% / /dev/sda1 99M 22M 73M 23% /boot /dev/mapper/gv1-vl1 30G 21G 7.1G 75% /var tmpfs 760M 0 760M 0% /dev/shm And in "free -m" I have this Code: total used free shared buffers cached Mem: 1518 1454 64 0 59 1089 -/+ buffers/cache: 304 1213 Swap: 2000 0 2000 As far as I know, since the friday nobody has touched the server and the only thing I did was simply restart my pc. I will continue to monitor the server during the day to verify that the problem is solved. Thank you very much for all your help and your time! P.D.:I have reviewed the "history" and an administrator has restarted the "Apache" and "MySQL". I supose he has made a modify of some config file of this services, but in the "history" trail does show nothing similar to "vi" or "gedit". He may have done this change by FTP or another way.
I talk to an administrator. He has replaced the entire virtual machine Centos 32-bit to a "Ubuntu Sever 10.10" and has installed the apache in worker mode and fast-cgi php. He has made in the weekend. Bone in the end the solution was to change the OS. XD
Even i am facing similar issues, i even tried using new clone against old server. still speed drops down at 10:30 pm and around 12:30 am. Solutino i try is to just restart mysql and httpd services Do any one has permanent fix for this
