...ount" was reached, Dovecot canceled all new connections. I've setup completely new configuration based on http://wiki.dovecot.org/TestInstallation and no error was produced but every time I closed telnet the imap process became defunct. So, I tried to trace what was happening with ktrace: ktrace -d -f log -p pid_of_imap_process In attached file is a part of ktrace output at the moment when I close telnet connection. What is interesting (at last for me, but I'm lamer) is an error: 1576 imap 1256902587.568406 CALL close(0xffffffffffffffff) 1576 imap 1256902587.568448...

According to "procstat -t", there is only one thread there: PID TID COMM TDNAME CPU PRI STATE WCHAN 37126 100724 dmake - 1 193 sleep - And trying to "ktrace -p 37126" returns (even to root, even in /tmp): ktrace: ktrace.out: Operation not permitted There are no problems ktrace-ing 33012, but nothing comes from there, as that process simply waits for its child. I guess, the child -- 37126 was (v)forked to launch a compiler or some such and...

It seems a php-extensions bug. If you comment the mhash.so in /usr/local/etc/php/extensions.ini as: ;entension=mhash.so all works fine and you don't get anymore httpd crash (signal 11) if you use 'apachectl graceful'. Maybe will be a good idea to open PR for this? I hope it helps someone.... (I'm very surprised that this isn't a documented bug in 7.0 yet) -- Thanks, Jordi

...y, > NULL) = -24 I need to make these error messages more user-friendly :( -24 is SSH_ERR_SYSTEM_ERROR, so it's likely failing to find/load the key for some reason. I'll make a patch to improve the error message, but in the meantime you could probably figure out the exact failure using ktrace/ktruss/strace and/or digging errno out of the core file. -d

Probably not, if you ktrace or similar you need only look for the last failing syscall (probably open) before the output of the error message. -d

...with test73, which worked fine. With the upgrade to test76, I lost the ability to SIGHUP dovecot when I rotated it's logfile. Dovecot would just die abruptly, not a trace in the log. I just upgraded to test77, but the problem is still there. I've put up my logfile and the last bit of a ktrace here: http://legonet.org/~griffin/tmp/dovecot/ The ktrace is partitial mostly because it contains usernames, I can edit those out and upload the hole shebang if that'll help. I'd appreciate any tips/pointers on this one! /Johan

Hi all I want to upgrade from 4.5-RELEASE to 4.8-STABLE. I cvsup-ed the source tree and then in /usr/src do 'make -j4 buildworld'.

hi all- I am currently running dovecot 0.99.10p2 on OpenBSD-3.4-snapshot. It has been very stable, but I have recently noticed that I am having problems when checking IMAP-SSL mail with Mac OS X clients. There are not problems using Mozilla or Outlook on Windows, but Mac clients (Thunderbird, Mozilla, Mail.app) all exhibit the same behavior - they can check and send mail, but I end up with a

Starting lockd. albert(11.1)[6] echo $? 0 albert(11.1)[7] service lockd status lockd is not running. I finally(!) thought to ask ktrace what's going on (as tailing /var/log/messages was completely unproductive, even after enabling rc_debug). So I tried: "sudo ktrace -di service lockd restart"; upon exanimation of the output of kdump(1), I see that the trace ends with: ... 2811 rpc.lockd NAMI "/var/run/logp...

...cation and one for vpopmail-auth: auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail } But the vpopmail dosn'nt work. I got the folowing in the log: Info: auth(vpopmail): vpopmail(stoffer at test.ek.dk): unknown user (stoffer at test.ek.dk) When I ktrace the dovecot process, it seams that it is trying to access the mysql db, but it ignores the settings in ~vpopmail/etc/vpopmail.mysql If I use the ports version of dovecot it works, but of course without the multiple auth capability since it is version 0.99...

...t a problem. However, in this scenario, "ssh-add -l" will only produce output to stdout if stdout is a tty. "ssh-add -L" reliably produces output to stdout. "ssh-add -l" reliably produces output to stdout _unless_ it can't parse one of the blobs from the agent. ktrace outputs of the working and non-working scenarios below. As you can see, in the broken scenario there's no I/O to stdout.

...il/ppgk.com.pl/%u/inbox In both cases, in user's directory, there will be an empty ~/Mail directory created, in addition to Mail and inbox. No idea about how sql or ldap would behave here, but global mail_location from dovecot.conf doesn't suffer from this issue (~ was expanded properly in ktrace dump). Chroot specification (/./) doesn't matter here. If I change mbox:~/Mail:INBOX=..... to mbox:/home/vmail/ppgk.com.pl/%u/Mail:INBOX=~/inbox then everything will be fine - no extra '~' dir. Thus my assumption it's not INBOX field related. Looking at ktrace, it seems that im...

Other than cranking up logging to debug2, is there a way to better tune logging on a server to see if I am running into max sessions ? On FreeBSD RELENG11 I am periodically seeing connections being refused- 3way handshake not completing or completing and then FINs. Typically, I have a hundred or so connections at one time, but they can bounce up to a few hundred on occasion. Without leaving the

Hello, I've tried to do a full text search on the inbox, it run fine, but the imap daemon started to eat all the CPU until I closed the email client.
