Crash Core Dump

https://pastebin.com/X8hQ4tc6 Describe the traffic that generated the bug

just a few of normal calls, nothing particular, calls launched by freeswitch originate command(fs<--sip invite-->opensips<--pstn-->cell phone but I do make some changes into my opensips.cfg, mainly nathelper things like nat sip ping , setbflag(), which I am not sure if the crash is cause by these.

This seems the same crash as #2777 , because of the the invalid list of of ongoing pings from nathelper.

thank you for the reply, but It looks #2777 not fixed yet

bogdan-iancu commented 2 years ago

yes, still working on that

Any updates here? No progress has been made in the last 15 days, marking as stale. Will close this issue if no further updates are made in the next 30 days.

thrill007 commented 2 years ago

thanks to bogdan-iancu, I disable nat ping as below and it works (the last statement):
if (nat_uac_test(18)) { fix_nated_register(); setbflag("NAT_BFLAG"); setbflag("SIPPING_ENABLE");

setbflag("SIPPING_RTO"); #TODO: this statement may cause crash, disabled!!

} no crash happens again, so far I got a work-around, the root cause is beyond I can find out, It looks I have to give up keep alive function
