It is for 4.1.
I have some ongoing work to commit soon on the master branch. if you confirm it is working fine, I will push this patch as well and backport to 4.1.
Cheers,

Hi All,
I wonder if some one could help me to diagnose a recurring issue?
It happens at random times/intervals and under varying load. But always, just before the time of crash, I see the same critical error in log:
CRITICAL: dialog [dlg_hash.c:841]: log_next_state_dlg(): bogus event 6 in state 1 for dlg 0xb0632134 [1367:5814] with clid '0695dd7a346188dd24e7520e6c01092c@sip.sipcentric.com' and tags 'as77c89620' ''
Analysing the core dump reveals:

In config, for pua_dialoginfo we are enabling the option "use_pubruri_avps" and setting "pubruri_caller_avp" and "pubruri_callee_avp" accordingly.
Therefore, in pua_dialoginfo.c it is using get_str_list() function to set dlginfo->pubruris_caller from the avp.
Could this be some race condition or something completely different?
Thanks in advance,
Charles
