Hello dear Subscribers!
I have mail-server (~ 20000 users, exim/cyrrus imap/webmail/LDAP auth)
under FreeBSD 5.2 box with last patches.
After 3 weeks of normal fly it`s crash twice a day.
systat -vmstat at ssh-console before crash shows this:

Can you tell me, why system used so much name-cache and network card
interrupts, I think it`s a cause of crash :-(
Any comments ?
