[cobalt-users] smtp not responding and sometimes restarts

[george <george@xxxxxxxxxxxxx>]

hi!
I have been running into problems recently with the SMTP shutting itself 
down every 15 minutes or so(10:30, 12:30, etc).

 it will run all night and then during the day it will start shutting 
itself down.I have not had a problem with this in 18 months. I also applied 
the latest cobalt patch today just to see if that might fix it. it hasn't.

sometimes it will restart itself after awhile. I have tried doing it 
manually with stop/start sendmail but it doesn't seem to make it start 
working again. sometimes even rebooting wont restart it.

I have looked through the cobalt archives for a couple of hours to see if 
others ran into the same problem. i saw one message with theI checked the 
15 minute problem but didn't see a solution.

I also looked at the /var/log/maillog but am not seeing anything strange 
that would be causing it. this is what i get when it crashes:

Sep  6 10:30:02 www imapd[3278]: imap service init from 127.0.0.1

when it is working, the sendmail section says :

Sep  6 12:00:05 www sendmail[2807]: NOQUEUE: Null connection from localhost 
[127.0.0.1]

is there some other files i can look at to see what is going on besides the 
maillog? if something was running in a loop, would it be shown in the 
maillog file?

thanks for any assistance!!
