For my part, it appears to be some sort of deadlock-y weirdness.  The 
server stays running, sort of.

It started basically right after the jb code was added, although of 
course there's no way of knowing whether there might be causality.

I'm betting on SIP being the culprit because the server always goes 
la-la at the same time one or another SIP traffic has just that instant 
been commenced, always.

Since the server doesn't die, there's no coredumps or backtraces to look 
at.

I'm doing my best to test it, but it is intermittent and I haven't found 
the predictor yet, beyond the aforementioned observation that a SIP 
channel just freshly activated seems always to be found at the scene.
