They seem to indicate a problem with gamin and its interaction with inotify and reports "Probably leaking memory".
The process referred to is gam_server.

The version of the Linux kernel installed is: linux-image-2.6.32-trunk-686 2.6.32-5

The Linux instance is running on VMware VSphere 4 and is using open-vm-tools.
It is an email server using the courier-imap-ssl daemon which makes use of FAM/GAMIN.
