[OpenSIPS-Devel] [ opensips-Bugs-2936343 ] 'opensipsctl fifo get_statistics all' crashes opensips

[Richard Revels]

Oh yeah.  I get same result.  I am using unix domain socket for MI.  get_statistics core: no problem.  get_statistics all dumps opensips.  No core generated.  Here is the opensips log when it happens:

Jan 21 18:08:19 guinea-pig1 osips-log[3931]: INFO:core:handle_sigs: child process 3943 exited by a signal 12 
Jan 21 18:08:19 guinea-pig1 osips-log[3931]: INFO:core:handle_sigs: core was not generated 
Jan 21 18:08:19 guinea-pig1 osips-log[3931]: INFO:core:handle_sigs: terminating due to SIGCHLD
