[SOLVED] Root cause analysis for server crash

Highmem lowmem - is this a 32bit kernel?
The 32bit kernel divides memory into segments, and if one of the segments runs out of memory, it invokes oom killer.
A 64bit kernel is one segment, you can utilize your memory much better.

Redhat Linux is the OS. I have configured the logs using the command atop 60. so the logs will be saved every 1 minute ?

If the OS is RHEL, and you're running a server, why not pay for and receive support?

If you're not paying for support, are you serious about your service?
What's notable in this thread is the lack of action by the sysadmin to get to the bottom of this. You haven't even verified what's using excessive amount of memory, and relying on a knowledgeable guess about samba. Can the box run a 64 bit kernel. What are the server specs?

Hi the crash happened on the server which has Debian OS and there the errors were. Is there any Debian support that I could raise case with vendor?
