similar to: Dovecot 2.2.10 crash / infinite loop bug

the new src/lib/ipwd.c introduced in 2.0.12 no longer compiles on solaris. Under solaris, the *_r routines doesn't pass in result as the last parameter and return errno - it just returns result. obviously a job for configure..... -- Roger Fujii<rmf at lookhere.com>

Hi, we run Dovecot 2.2.13 on Debian Wheezy with a couple thousand mailboxes. We have two users that repeatedly trigger an OOM condition with IMAP.

Greetings, Post 12689:7f5735ab7c35 / 12690:02829f7f79c7 dovecot uses the reentrant version of get(password/group)* related functions. There are two variants of these functions on Solaris. To get the variant used by dovecot code based you need to define _POSIX_PTHREAD_SEMANTICS (see attached manual page). Initially I defined this just for the compilation of lib/src/ipwd.c, and got the code to

After recently adding the -f parameter to the call to the deliver command which is called by Postfix, I found that e-mail with a null return path (MAIL FROM:<>) was causing Dovecot deliver to SEGFAULT. I verified this by making this patch to deliver.c (notice I fixed a typo here, too): *** deliver.c.orig Fri Oct 13 07:32:28 2006 --- deliver.c Fri Oct 27 21:26:08 2006 ***************

Timo et al., I haven't been reading the list in a while, but wanted to report back that we've transitioned to dovecot 1.0.15 and things look to be working very nicely. The platform is Solaris "Nevada" running on x86. I have been saving up a couple of issues to bring to your attention. On our server, we gather all core files, and so we get a good taste of the different things

I thought I had cleared out the corruption I had before - perhaps I was mistaken. What steps should I take to help locate these issues? Currently using 2.1rc1. I see the following errors in my logs, including out of memory and message size issues (at 15:30): Jan 4 05:17:17 bubba dovecot: indexer-worker(user1 at domain.com): Error: Raw backtrace:

dovecot-2.2.13 running on Solaris-10, app 5000 concurrent connections, and a pretty standard config where passdb is set up with driver = pam. We have had some situations where an auth-worker gets into a loop, the load on the server rises and the auth-master seems blocked untill finally no new imap nor pop session are accepted. A 'doveadm reload' restores normal operations. With debug

Hi, I have some out of memory errors in my logs (file errors.txt attached) I'm using dovecot 2.0.19, I can see some memory leaks fix in hg after the 2.0.19 release but they seem related to imap-login service, I attached my config too, is something wrong there? Should I really increase the limit based on my settings? Can these commits fix the reported leak?

Hi. In my setup exim delivers mails to dovecot using LMTP. In one LMTP session exim can deliver up to 200 recipients (batch_max set to that value). Now the problem is that sometimes 256MB is not enoug for dovecot lmtp to handle incoming emails. My questions: - how big memory limit should be for lmtp? I was thinking that lmtp (more or less) simply reads from one descriptor and writes to file,

Hi Timo, just to report that . dovecot-1.2.12 which ran fine for several month . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC amd64) . using Maildir (mailboxes, control and indexes on NFS) has crashed this morning on our server. I found nothing special in the logfile. Attached are dovecot -n output and a gdb backtrace of the core file. Thanks -- Thomas Hummel | Institut

Do these errors indicate a memory leak? I see them in the logs a few times per day on each of our servers, running CVS dovecot-20060924...

Do those users have mailboxes extra ordinary large or is one message of them extra ordinary large? Jun 23 12:53:21 lxmhs74 dovecot: imap(USER):

Hi! I've upgraded from 2.0.11 to 2.0.12. I've experienced errors during delivery with dovecot-lda. The error log attached contains the errors. Since then I had to downgrade to 2.0.11, to make it work again. When starting 2.0.12, it couldn't chown() the files under /var/dovecot (eg.: dict) to the user specified in the configuration file. Configuration: # doveconf -n # 2.0.11:
