Check for bdf & mount -a output.. something is smelling bad, might be corrupt file system..
run dmesg and confirm..

Good luck

Hi,
this may be a hardware problem, however:
1. check where mail error messges go to by looking at the /etc/syslog.conf file
2. Check that file
3. Check syslog.log
4. Are any emails being sent, or is the whole sendmail process stopped.

Hi all
thanks. Attached is the bdf output and syslog file for further analysis

Hi,
nothing unusual I can see in these logs.
Can you please also check the file used for mail logging. Mine is
/var/adm/syslog/mail.log
See my earlier posting (point 1,2 and 4)

Looking at output I believe IO error belong to a different file system.. can you look at vx_nospace messages and see if any mail flow is stuck due to that and clear it off..

Otherwise there is nothing else I can doubt about..

Regards

With 7,000+ messages in the queue, you do have a problem.

Run ls -l /var/spoo/mqueue to verify that's where all the messages are being held. If you get I/O errors with that, run fsck on /var.

To diagnose sendmail try this:

to force-flush the mail queue:
sendmail -v -d8.20 -q

to debug the sendmail daemon:
sendmail -v -d0 -d1 -d0.4 -d1.5 -d2 -d6 -d6.5 -d10 -d11 -d30 -d45 [your email address here] /tmp/maildebug.log 2>&1

where testmailfile is a text file with a one or two line message in it.
