Hi, I am experiencing frequent system hangs, hard kernel panics, etc almost thrice a day. The system would be totally unresponsive and the only way is to reboot is hard power recycling (plug out the power cable and plug in back after 30 secs). I enabled kdump, but unfortunately the kdump files are as huge as 16GB and unable to analyze. The repeated errors I get in the /var/log/messages is I have CentOS release 5.5 (Final) with kernel-2.6.18-194.3.1.el5. The hardware is HP dc7900 with 16 GB RAM, Intel Core 2 Duo E8400/3Ghz/4GB RAM, 160GB HDD. I have installed MySQL builds from Percona viz Percona-XtraDB-1.0.6-10.2-5.1.45-10.2.rhel5 Percona-Server-server-51-5.1.47-rel11.1.51.rhel5 Percona-XtraDB-1.0.3-5-5.1.34-5.rhel5 Percona-Server-shared-compat-5.1.43-3 Percona-Server-client-51-5.1.47-rel11.1.51.rhel5 Percona-Server-test-51-5.1.47-rel11.1.51.rhel5 Percona-Server-devel-51-5.1.47-rel11.1.51.rhel5 Percona-Server-shared-51-5.1.47-rel11.1.51.rhel5 The uname -a produces Linux blr-cos-mdb01.digi.com 2.6.18-194.3.1.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux What could be the issue and how to resolve it ? Regards Prashant
Issue resolved. BAD ... BAD MEMORY, after removing one if the DIMM's, the server no longer crashes. I wonder how memtest passed the Memory !!!!
