Berkeley DB4 can;t allocate memory errors

[Aidan Evans]

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

	Sep 27 22:50:07 imap imapd[32227]: DBERROR db4: Lock table is out of
	available locker entries

	Sep 27 22:50:07 imap imapd[32227]: DBERROR db4: /var/imap/tls_sessions.db:
	Cannot allocate memory

	Sep 27 22:50:07 imap imapd[32227]: DBERROR: opening
	/var/imap/tls_sessions.db: Cannot allocate memory

	Sep 27 22:50:07 imap imapd[32227]: DBERROR: opening
	/var/imap/tls_sessions.db: cyrusdb error


	Oct 1 04:02:48 imap lmtpd[11979]: DBERROR db4: Unable to allocate
	memory for transaction detail

	Oct 1 04:02:48 imap lmtpd[11979]: DBERROR db4:
	/var/imap/deliver.db: Cannot allocate memory

	Oct 1 04:02:48 imap lmtpd[11979]: DBERROR: opening
	/var/imap/deliver.db:  Cannot allocate memory

	Oct 1 04:02:48 imap lmtpd[11979]: DBERROR: opening
	/var/imap/deliver.db:  cyrusdb error

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?).
