hi ther, i used "the perfect server centos 5.5" , and iv'e had crashes when my cpu/ram reach 50%/20% i dont know if this is related, but I wanna know if ther is any way to check for the reason for this crash... thank you very much.
You may be able to try /var/log/kern or "dmesg". Each should be able to give you useful information about crashes. You may even want to look for any core dumps created by the crash and analyze them.
lol im so newB, where is the core dumps located? and i dont understand what i see in the crash log, but ill google it ,,,
You could install munin (see http://www.howtoforge.com/server-monitoring-with-munin-and-monit-on-centos-5.2 ) - the graphs might give you a hint why your system crashes.
