Hi, Larry

Hi, Larry

It's better you can provide the core dump file for woogeen_sip when error happens. Please follow below steps in case you don't know how to collect core dump file.

“ulimit -c unlimited” to make it effective immediately in current console;

Modify the /etc/security/limits.conf (on Ubuntu) or /etc/security/limits.d/xxx.conf to add the following lines

“* soft core unlimited”

“* hard core unlimited”

Then execute command below:

echo ‘/tmp/core.%e.%p.%t’ | sudo tee /proc/sys/kernel/core_pattern

if crash happened, related coredump file would be generated in /tmp/ folder with file name.
