I have also been experiencing memory leaks, such that the kernel has
been taking drastic action by killing processes starting with nagios and
often including httpd, sshd etc.  This all seems to happen at about 4:45
every morning.  A reboot solves the problem and everything starts up
again, but yesterday I decided to reboot using the single processor
kernel (most of our nodes are dual processor, some are dual core as
well) and there is no sign of a memory leak today !

Does that give anyone any clues ?
