[Dovecot] expire plugin error

[Michael Lechtermann]

Hi,

I am using the db backend for the expire plugin and found the following
error message in the logfile:


dovecot: Jan 22 10:10:55 Error: dict: secondary db: unable to allocate
space from the buffer cache
dovecot: Jan 22 10:10:55 Error: dict: Failed to initialize dictionary
'expire'
dovecot: Jan 22 10:10:55 Error: IMAP(xxxxxxxxxx):
read(/var/dovecot/dict-server) failed: Remote disconnected


Anyone know how to fix this? I do not want to use SQL as backend, that
would be overkill.
