IOERROR: mapping /srv/imap/config/annotations.db.NEW file: Cannot allocate memory

[Jan Kowalsky]

Hi all,

for a few days all time creating or deleting folders we get an error in
mail.log:

Dec 16 18:28:17 mail imap[10078]: IOERROR: mapping
/srv/imap/config/annotations.db.NEW file: Cannot allocate memory
Dec 16 18:28:17 mail imap[10078]: Fatal error: failed to mmap
/srv/imap/config/annotations.db.NEW file
Dec 16 18:28:17 mail imap[10078]: twoskip:
/srv/imap/config/annotations.db closed while still locked

We can create mailboxes - but cannot delete them anymore.

The annotations.db is twoskip format and we are running cyrus 2.5 (with
kolab).

Any Idea?

Thanks and best regards
Jan
