sonewconn issue?

[Steve Kargl]

Last night my system became wedged.  Inspection of/var/log/messages
revealed 290 messages of the form

Dec 10 19:27:49 troutmask kernel: sonewconn: pcb 0xfffff8000a76c4b0:
   Listen queue overflow: 16 already in queue awaiting
   acceptance (1 occurrences)
Dec 10 19:28:55 troutmask kernel: sonewconn: pcb 0xfffff8000a76c4b0:

   acceptance (9 occurrences)

   acceptance (1 occurrences)

During this time, I could connect to the webserver on the system.
ssh into the box would connect, but I never got an actaul session.
This morning I found the console unresponse.

Any suggestions for identifying the rogue process?
