HELP SMTP_SUBMIT server is not responding

Question

All 4 of my inbound mail servers (MTA) are throwing SMTP_SUBMIT server is not responding errors!
These are all Solaris 9 boxes using
Sun Java(tm) System Messaging Server 6.2-3.03 (built Jun 27 2005)
libimta.so 6.2-3.03 (built 01:16:06, Jun 27 2005)
SunOS msgmta-4 5.9 Generic_122300-38 sun4u sparc SUNW,Netra-240
I found other postings like this on this site, but they don't seem to apply to my servers. I checked the job_controller.log,
and it's empty.
The default log shows:
[23/Aug/2010:10:30:10 -0800] msgmta-4 msprobe[28092]: General Critical: SMTP_SUBMIT server is not responding
[23/Aug/2010:10:35:10 -0800] msgmta-4 msprobe[28545]: General Error: function=getserverresponse|port=587|error=failed to get server banner
I did the obvious thing and stopped msg and restarted it, however, this did not resolve the problem.

Answer 1

thank you. I found out from a co-worker that this was not the showstopper that I thought might have been the problem which turned out to be a hung process on one of the other servers. I thought that there was a way to mark this as resolved, but for some reason I am not finding it right now.
