[Dovecot] Re: Dovecot died due to some SSL related error
(Sorry, just joined the list, can't reply in the original message from Feb 4.)
Hi, Dovecot (pre-compiled version of Fedora Core 1, configured for Maildir) is running fine for me since a few days. It happened now twice to me that dovecot died with the following error message in /var/log/maillog:
Feb 4 11:18:27 hundehuette imap-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded Feb 4 11:18:27 hundehuette dovecot: Login process died too early - shutting down
As these previous log messages indicate the login was working before without any problem: Feb 4 11:02:37 hundehuette imap-login: Login: andrea [192.168.2.138] Feb 4 11:05:56 hundehuette last message repeated 30 times Feb 4 11:09:02 hundehuette last message repeated 15 times Feb 4 11:12:08 hundehuette last message repeated 15 times Feb 4 11:15:15 hundehuette last message repeated 15 times Feb 4 11:18:21 hundehuette last message repeated 15 times Feb 4 11:18:26 hundehuette last message repeated 12 times
Dovecot is running as user "dovecot" who does not have a ~/.rnd file
Any idea?
Thanks, Christof
Hi,
No idea, but I'm getting the same thing, at least once a day, sometimes several times a day. I tried putting a .rnd file in /var/libexec/dovecot, no help.
Fedora Core 1.0
dovecot-0.99.10-6
openssl-0.9.7a-23
About 20 users, using pop, pops, imap, imaps.
I had to run a cron job that checks every minute to see if dovecot is running, and restart it if it isn't. I'd love to get this figured out, though. I see another message about this in the list archives, at the end of January. I'll post if I find anything...

Following up to myself - per an email request from a new subscriber, here's my script and crontab entry for checking and restarting dovecot on Redhat/Fedora. This catches a crashed dovecot at least once a day, sometimes several, all due to the "PRNG not seeded" thing on Fedora.
I could have just let the cron daemon email the results to root like any other cron job, but I wanted a copy to my own account. Running on a couple of hosts - MYHOST replaced with actual hostname, MY-PERSONAL@EMAIL.ADDR replaced with ... well you get the picture.
Hope it's useful, Rob
root Crontab:
## Run once every minute, always.
/root/CronJobs/cron.chk_dovecot >/dev/null 2>&1
Script: /root/CronJobs/cron.chk_dovecot
#!/bin/bash
if ! pgrep -x dovecot
then
if [ -f /var/lock/subsys/dovecot ]; then
if rm -f /var/lock/subsys/dovecot ; then
MsgRmLock="Lock file /var/lock/subsys/dovecot removed."
else
MsgRmLock="Unable to remove lock file /var/lock/subsys/dovecot."
fi
else
MsgRmLock="No lock file found: /var/lock/subsys/dovecot."
fi
if /etc/init.d/dovecot start; then
MsgStart="Dovecot started."
else
MsgStart="Unable to start Dovecot."
fi
if pgrep -x dovecot; then
MsgRunning="Dovecot running."
else
MsgRunning="Dovecot not running. To restart, run (as root):
/etc/init.d/dovecot start"
fi
mail -s "MYHOST DOVECOT NOT RUNNING date '+%R %D'" -c root MY-PERSONAL@EMAIL.ADDR <<EoMaIl
On MYHOST, the command "pgrep -x dovecot" returned false, indicating
that dovecot is not running.
Restart attempted. Results:
$MsgRmLock
$MsgStart
$MsgRunning
EoMaIl
