[CentOS] libkeyutils.so

Hi,

I had setup yet another qmail toaster on a centos 5 x64. While trying to
send a test email, I encountered this error.

@400000004809bc511c396914 /var/qmail/bin/qmail-smtpd: error while loading
shared libraries: libkeyutils.so.1: failed to map segment from shared
object: Cannot allocate memory

Any idea?

Thanks and best regards
