Hi, I'm one of those people who still need to maintain * 1.2 systems and cannot easily upgrade. :-( My 1.2 systems were very stable until I upgraded from 1.2.37 to 1.2.40. I have made some changes within my dialplan but nothing unusual. Today I've had a crash: https://issues.asterisk.org/file_download.php?file_id=25571&type=bug Yesterday I had another: https://issues.asterisk.org/file_download.php?file_id=25572&type=bug Could anyone please have a look at these gdb traces? Other than that the traces seem to point to ast_expr2 and chan_iax2, I don't really have a clue as to why Asterisk crashes. Any ideas? Vieri
