Hi folks,
Here is the scenerio. I got a new dedicated server from softlayer.com 3 months ago, it's been running perfectly ever since. So, last week I decided to upgrade the memory from 2GB to 3GB. A couple of days later, it crashed, then 3 days later it happened again. The first time, server came up after a remote reboot. However, the second timem, it wouldn't come up. The tech said the memory was not seated correctly. It booted up fine after he re-seated them. And then today, it crashed again.
The system specs:
Intel Xeon 3060
3GB ECC DDR memory
2x250GB SATAII HDD
CentOS 4.5 32-bit with Cpanel 10
Kernel 2.6.9-55.ELsmp #1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux
I'm suspecting it's due to faulty memory. I noticed that swap usage is always greater than .5% before the crash. 2GB is allocated to swap partition. Could it have anything to do with swap usage? How about the kernel version, anything that may have caused it to crash/hang? I thought that having 3GB of RAM is odd since most servers have an even numbered amount. Maybe I should upgrade to the latest stable CentOS kernel.
I asked the tech to swap out the ram and test the memory. If you guys have any ideas, please post it here. Thanks in advance.
