Cannot allocate memory

This is a fresh install on CentOS 5 x86_64. Only one vps using minimal CentoOS 5 x86_64 template. This error comes up whenever an smtp connection is made to qmail:

/var/qmail/bin/qmail-smtpd: error while loading shared libraries: libresolv.so.2: failed to map segment from shared object: Cannot allocate memory

Here is strace on qmail-smtpd

SOLVED
It turns out the softlimit () setting was too low for qmail-smtpd. Increasing the value in /var/qmail/supervise/qmail-smtpd/run fixed the issue. Nothing to do with openvz :)
