Hi Timo and others,
I'm using test32 since today and I'm getting this error once every 2 hours or so:
dovecot: Jul 30 20:21:26 Error: IMAP(jens@gutzeit.at): open(/var/mail/data/jens/jens@gutzeit.at/maildir/.INBOX.Gentoo.Security/dovecot-uidlist) failed: Too many open files dovecot: Jul 30 20:21:26 Error: IMAP(jens@gutzeit.at): file maildir-uidlist.c: line 147 (maildir_uidlist_deinit): assertion failed: (!UIDLIST_IS_LOCKED(uidlist))
The problem is not specific to this mailbox.
I hadn't this problem with the stable releases and I've also not set any special limits for the dovecot processes.
I'm using a grsec pathed kernel (linux 2.6.7), the kern log says: grsec: attempted resource overstep by requesting 1024 for RLIMIT_NOFILE against limit 1024 by /usr/local/libexec/dovecot/imap[imap:19114] uid/euid:1011/1011 gid/egid:448/448, parent /usr/local/sbin/dovecot[dovecot:7799] uid/euid:0/0 gid/egid:0/0
Does dovecot really need more then 1024 filedescriptors or is it a bug?
If you need more information just ask.
best regards, Jens
