high memory problems with imap
What Debian Linux Kernel works best for High Memory ( > 4GB) machines
that are
under heavy io loads ?
I have a courier/postfix maildir IMAP mail server with 10GB of RAM.
Occasionally, the memory gets all chewed up and it becomes unusable. I
think it becoming unusable because of buffer bounces.
However, the documentation tells me that the
virtual memory allocation and bounce buffer problem was fixed in 2001.

Is anyone using high memory on servers with heavy loads ?
I am running a 2.4.22 kernel on a machine with a 4GB. This machine is
also under a heavy load as it servers up web-mail, but I have no
problems with it.
However things seem to turn experimental with more than than 4GB of RAM.
