In both cases, the thread is waiting in recvmsg.
Guessing a bit, I would suspect that you have some form of DNS or reverse
DNS issue occurring on your systems, most likely with a very long timeout.
I can't speculate why changing a kernel version would cause this problem,
although given the scope of such a change, it isn't terribly surprising
that some DNS related behaviour would be impacted.
This isn't a bug in Asterisk. Later versions of Asterisk (and different SIP
stacks) can mitigate long running DNS queries to an extent, although it is
still going to cause problems.
