Subject: Version 3.8.4 hangup on shutdown
Date: 03/02/25 15:06:20
I'm running Cyrus IMAPd version 3.8.4 on FreeBSD. I recently upgraded
from Cyrus 3.4, which was running fine.
3.8.4 runs fine, but I'm having trouble shutting down. I'm using the
default startup script installed on FreeBSD from ports, which seems to
basically just do kill -TERM on master.
It seems to begin shutting down fine:
Feb 3 14:36:58 mail imapext[73022]: graceful shutdown
Feb 3 14:36:58 mail http[75500]: graceful shutdown
Feb 3 14:36:58 mail imapext[75445]: graceful shutdown
Feb 3 14:36:58 mail lmtpunix[75477]: graceful shutdown
Feb 3 14:36:58 mail http[75504]: graceful shutdown
Feb 3 14:36:58 mail http[75494]: graceful shutdown
Feb 3 14:36:58 mail imapext[75376]: graceful shutdown
Feb 3 14:36:58 mail http[75495]: graceful shutdown
Feb 3 14:36:58 mail pop3sext[75479]: graceful shutdown
Feb 3 14:36:58 mail lmtpunix[75478]: graceful shutdown
Perhaps this is unexpected:
Feb 3 14:36:58 mail idled[57259]: graceful shutdown initiated by
unexpected process 57237
Process 57237 is the master process ID in this case. I'm not sure why
it's unexpected.
After a few gracefully shutdown messages, master gets stuck, running at
100% of CPU, in this code:
Process 57237 stopped
* thread #1, name = 'master', stop reason = signal SIGSTOP
frame #0: 0x000000000020e90e master`child_janitor(now=(tv_sec =
1738587528, tv_usec = 269269)) at master.c:1541:26
1538
1539 while (i-- > 0) {
1540 p = &ctable[janitor_position++];
-> 1541 janitor_position = janitor_position % child_table_size;
1542 while (*p) {
1543 c = *p;
1544 if (c->service_state == SERVICE_STATE_DEAD) {
I don't see any instances of lmtpd, imapd, pop3d, or httpd running.
This happens fairly often when shutting down, but not always.
Any ideas on how to fix this? I'm happy to assist with any debugging or
more information.
Thanks,
Mark
