Joegen,
We recently upgraded a bunch of our servers to 4.4.0 update #18,
and while this issue doesn't occur as frequently, we are still
experiencing it.
I was going to try running a version that has the original patch
(any combination of CR-LFs in a keepalive message) and see if that
gets us anywhere, but not being able to produce a hang on demand
kind of limits our testing options for this.
Not being totally convinced it is the keepalive processing, are
there any other places we could look for the root cause of this
problem?
Thanks,
Andy

Joegen,
Actually, it looks like we have the keepalive.sessionTimers
option turned off for all our phones anyway. I looked in the
pcap we have from a hang just this morning and I didn't see
any messages matching the PUBLISH method. I can send you these
off list if you'd like.

I've taken a quick look at the NAT traversal plugin and it
seems to be not accounting PUBLISH as a potential stream
modifier. But it is not clear to me how it would cause a hang.
Can you disable session-timers in the phones and see if that
somehow lessens the occurence of this incident?

Joegen, George,
I noticed some messages in my sipXproxy log from a
hang on a
customer system just today, which may or may not be
pertinent. Besides the parsing errors, I also see
messages
such as this immediately before the hang:

Since this has been happening to some of our customers
more
than once within a 24 hour period, in order to keep them
from cancelling with us we've had to resort to a watchdog
script which sends OPTIONS messages to the servers
periodically and restarts sipXproxy if it fails to
respond.
Obviously this is just a band-aid workaround until we can
resolve this issue, since this means they incur
approximately 3-4 minutes of service interruption
every time
this happens.
