Description Thomas J. Baker 2011-01-07 15:17:52 UTC 
I'm running F14 with all updates and since going to 14, my sendmail-8.14.4-10.fc14.x86_64 dies at around 4:00am on a regular basis with the following error:

Now I know this is when cron.daily runs, I do get over 100 logwatches sent to me at that time, and since it doesn't happen every night, it seems more load related than an easily reproducible bug. After it happened a few days ago, I turned log level up to 20 but it didn't produce any more enlightening error messages. 

Are there sendmail config file tweaks that may help?
Comment 1 Jaroslav Škarvada 2011-01-18 23:18:59 UTC 
Do you limit number of sendmail child processes (confMAX_DAEMON_CHILDREN)? Are you using logwatch? Is there any specific sendmail settings in you config differing from the defaults?

I tried (several times) to handle more than 100 logwatch emails simultaneously on my testing machine - it was kicked into knees for couple of minutes but I was not successful to reproduce this.
Comment 2 Thomas J. Baker 2011-01-19 15:50:31 UTC 
I have these set:

define(`confMAX_DAEMON_CHILDREN', `50')dnl
define(`confCONNECTION_RATE_THROTTLE', `3')dnl

I am using logwatch and I have a couple of dnsbl's defined as well and clam-av milter and spamass-milter configured. I receive a lot of mail on this machine.
Comment 3 Jaroslav Škarvada 2012-01-26 08:24:41 UTC 
F14 is EOL, is it still an issue with current Fedoras?
Comment 4 Thomas J. Baker 2012-01-31 13:04:16 UTC 
No, it's fine now.
Comment 5 Jaroslav Škarvada 2012-01-31 13:49:20 UTC 
Thanks for info, closing according to comments 3, 4.
