I do not need the full log, but neither is the partial backtrace providing
enough information. We will either need to increase the 10s to 100s in
melted_local.c:sigsegv_handler(), or run melted in gdb and issue 'thread
apply all bt' within gdb when it crashes. I will try to recreate the
problem based on some MVCP usage patterns I see from your log above. I
encourage you to do the same. In your system, Is the client that is calling
USTA on a different thread/process & socket than the client calling CLEAN
and APND?
