[j-nsp] SRX3600 weirdness

Sat Apr 27 17:55:13 EDT 2013

I’ve been able to make some more sense of the problem.  After clarifying a few things with the database admins, the issue isn’t sending mail.  It’s some ticketing system that receives email approves, so it’s constantly checking an Exchange mailbox.  That’s where the IMAP traffic comes in.

After enabling the flow trace and waiting for it to have another problem, I was able to see some “SPU invalid session” messages.  These seem to be the only indication of a problem so far.    These seem to occur on and off throughout the day, but there were a lot of them right around the time the problem was reported.  Can’t seem to find much on the Net about these messages, at least in regards to regular TCP flows.  There seems to be a lot about SIP or SCCP, but we’re dealing with IMAP and there are no ALGs turned on for this.
