The fix for this has now been merged as 1.155.2.22. As there have been no
new reports of UNIX domain socket problems in the last couple of days, it
sounds like the MFC of the last batch of fixes and cleanups has not lead to
problems.
I've just upgraded my kernel to the latest, to include the MFC'd code above
...
Yes -- I was very specific in my e-mail regarding the MFC's that they were not
believed to address the problem you are reporting. I think we have a leak in
the way some edge case is handled with regard to UNIX domain socket shutdown.
What would be really nice to know is if that persists in 7-CURRENT, in which
we've redone the way the socket life cycle works. However, I don't know if
you are able to tolerate booting a 7-CURRENT kernel in your environment...?
Did we determine whether backing out to before the unpcb socket reference
count change made any difference for you?

Just before rebooted, as I've done the past couple of times, I shutdown
everything on the server, so that there were minimal processes running ...
based on the last one, and this one, it looks like the number of "Active
open sockets" is ~4000 ... last time, I was up to 11k sockets open, and it
drop'd to ~7000 once all jails were shut down, but, as reported to
Robert/John, there was a java process in a soclose state, so I wasn't 100%
certain there ...
This time through, I started at about 8800 sockets open, and shut down all
processes, including all java processes ... using ps auxlw, I checked for any
processes in a soclose state, and there were none ... I waited a full 10
minutes to let things 'settle', and after 7 of those, it had drop'd down to:
mars# uptime ; sysctl kern.ipc | grep sock
2:18PM up 1 day, 13:26, 5 users, load averages: 0.00, 0.47, 2.57
kern.ipc.maxsockbuf: 262144
kern.ipc.sockbuf_waste_factor: 8
kern.ipc.numopensockets: 4835
kern.ipc.maxsockets: 12328
And stuck there for the remaining 3 minutes before I rebooted ... which is what
leads me to believe that there are about 4000 active sockets on this server
when everything is running ...
