I've responded on the issue but the backtrace you've provided makes it 
appear as though the issue is actually in ODBC, which since chan_sip is 
using it in your deployment it causes it to lock up (why exactly is 

Since it's separate you should create a new issue. If you don't want to 
I can do so tomorrow. The complete console output (with debug going to 
console in logger.conf and core set debug 3) as well as the 
configuration would also be useful.
