I get some trouble with my new VPS.

server use
# uname -a
Linux 2.6.8-022stab078.10-enterprise #1 SMP Wed Jun 21 12:20:51 MSD 2006 i686 i686 i386 GNU/Linux

vps is centOS with apache, mysqld, php and vsftpd

We have 5 vps on this server and they works ok. But my new vps crashes every day with memory.
It run ok after restart by #vzctl stop 104

That i get when server crashes:

on vps ssh login: (some times i can't login by ssh on vps)
--------------------------------
Last login: Mon Jan 29 11:07:39 2007

-bash: [: =: unary operator expected
/bin/hostname: error while loading shared libraries: libc.so.6: failed to map segment from shared object: Cannot allocate memory
dircolors: error while loading shared libraries: libc.so.6: failed to map segment from shared object: Cannot allocate memory
--------------------------------

on main server
--------------------------------
#/usr/sbin/vzctl exec 104 service sshd status
bash: error while loading shared libraries: libtermcap.so.2: failed to map segment from shared object: Cannot allocate memory
--------------------------------

I made search on forum and found only this thread http://forum.openvz.org/index.php?t=tree&goto=8153&& amp;srch=libtermcap#msg_8153
but I don't have mod_secure in apache

You have a great resource shortage in all VEs!
Increase limits/barriers for parameters, which have failcounters in /proc/user_beancounters.

HTH,
Vasily
