We'll need a backtrace to triage the issue.

Debugging deadlocks:

Please select DEBUG_THREADS and DONT_OPTIMIZE in the Compiler Flags
section of menuselect. Recompile and install Asterisk (i.e. make install)

This will then give you the console command:

core show locks 

When the symptoms of the deadlock present themselves again, please provide
output of the deadlock via:

# asterisk -rx \\\"core show locks\\\" | tee /tmp/core-show-locks.txt

# gdb -se \\\"asterisk\\\" <pid of asterisk> | tee /tmp/backtrace.txt

gdb> bt
gdb> bt full
gdb> thread apply all bt

Then attach the core-show-locks.txt and backtrace.txt files to this issue.
Thanks!
