Hy,
I have a rather strange problem with a OpenVPS server ...
The HN is a Core 2 Duo E4500 @2.20 GHz with 3Gb of RAM ...
I've created a VPS with 1Gb of RAM and installed cPanel inside it ... and everything went smooth ... I even run a unixbench, just to see how would it perform ...
I've put a site on this server (ok, it is a rather heavy application... but the 1Gb i reserved for it should be enough) ... and that also worked fine for a few hours ... than the problem:
Now my apache server complains about not having enough memory:
/usr/bin/php: error while loading shared libraries: libXdmcp.so.6: failed to map segment from shared object: Cannot allocate memory
But this is not suported by anything I see on that server/VPS...

On the HN there is nothing else running ... on the VPS I have:
init-+-cpanellogd
|-cpsrvd-ssl
|-crond
|-dbus-daemon
|-dovecot-+-dovecot-auth

|-pure-ftpd
|-queueprocd
|-snmpd---{snmpd}
|-spamd---spamd
|-sshd
|-tailwatchd
`-vzctl---bash---pstree
I really don't get what is happening ... everything else is working fine, my apache server is serving static pages just fine ... At first I thought it was a apache/php thing so I recompiled ... no luck there ... (restarting the HN/VPS did not help either)
Thank you
PS Both the HN and the VPS have CentOS 5 X86_64
