Hello!
Unfortunately we are seeing lately (2-3 times during a day) that
asterisk seems to hang up somehow - no new calls can be made and
sip show peers and other commands show no obvious problem. We then
recompiled 1.2.7.1 with all the DEBUG_ turned on in the makefile
and now we see the following messages:

This continues until someone stops asterisks and restarts it.
Stepping back to version 1.2.4 solves the problem of a hanging
asterisk, however occassionally we see 5-15 seconds runs of
May 23 00:28:35 DEBUG[3212] chan_sip.c: Failed to grab lock, trying
again...
messages in the log file and during this time no call processing
happens. Then asterisk recovers from this locking state and
continues. 1.2.7.1 hangs in there forever.
Any clues as to why this happens?
