Hello,

FreeSwitch offen crashs every one or two days ,and the problem has lasted for about 2 months, the OS is centos 7.4,the FS version is 1.10.7 , the sofia-sip is latest version 1.13.7 ,and rebuilt last week,proc architecture is : 12 Intel(R) Xeon(R) Bronze 3204 CPU @ 1.90GHz。

the call flow is a simple inbound call to IVR , and then to callcenter according to digit dialed , no any call flows are involving localhost in setup , no local resolver used.

file /etc/resolv.conf is empty.

file /etc/hosts : 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

the error messages in /var/log/messages is : May 4 20:34:52 localhost kernel: traps: freeswitch[92647] trap divide error ip:7f2c9e58381a sp:7f2c7d58c070 error:0 in libsofia-sip-ua.so.0.6.0[7f2c9e457000+1ca000] May 4 20:34:54 localhost freeswitch: #33[m#033[32m2022-05-04 20:34:34.034071 98.97% [INFO] switch_cpp.cpp:1465 From Lua callcnt_say_agent_num.lua: caller_uuid: f May 4 20:34:54 localhost systemd: freeswitch.service: main process exited, code=killed, status=8/FPE May 4 20:34:54 localhost systemd: Unit freeswitch.service entered failed state.

would you please tell me how to capture the messages , or messages which are involving localhost in setup , and how to check whether local resolver is set.

please help ,thank you! backtrace1107.log

can you try this PR ? https://github.com/freeswitch/sofia-sip/pull/130 . you must rebuild and reinstall sofia-sip. then rebuild FS. the bug looks related to the code resolving ipv6 / AAAA

thank you ,I try it .
