I have been having a problem with my webserver over the last week or two. The symtoms are that the server runs our of RAM and becomes unresponsive, even when I reboot the server after a few minutes the same behaviour occurs however sometimes a reboot seems to fix the problem. There is nothing in the syslog or any other logs to explain this behaviour and SNMP doesn't report any spikes in load average or memory usuage before the server goes 'down''
The server has 4 Gb of RAM and in normal usuage the server doesn't use more than have of this (as reported by 'free').
I'm pretty sure that the server hasn't been rooted and I don't appear to be being dos's when these problems happen.
I have suggested to my provider (ev1) that there is possibly a hardware issue here buit can anyone suggest any reason why something like this would happen with cpanel?
I am running latest stable on Redhat 7.3
