Berkeley DB4 can;t allocate memory errors

[Su Li]

>From what I experienced. The delivery speed exceeds the capacity of IMAP
server. There are a lot of lmtpd process and your are really ran out of
memory. Just limit the speed of delivery from Sendmail. Or try tuning up the
performence of IMAP server.

  Anybody seen errors like this before and have suggestions about what to do
about them?

They're happening thousands of times a day so I guess whatever the problem
is, it's not going to just go away.

  I assume the databases are okay, just not being used (or are they broken
which is causing the error?).
