The CRITICAL log message is a side effect of the crash, not the reason of the crash.

First I suggest you upgrade to at least to latest 5.0.x, because there were many fixes after 5.0.1, and what you get may be fixed already. Such upgrade requires to deploy new binaries and restart.

Even better will be to upgrade to a maintained release, such as 5.3 or 5.2. This may require to change config file and database structure, but you have more fixes include.

After upgrade, if you still get the crash, grab the backtrace with gdb from the core file -- logs suggest it was generate:

ALERT: <core> [main.c:747]: handle_sigs(): core was generated

Hello everyone,

I have a problem in production environment where I have two SIP Proxies and both had the same problem but I don't have a ideia about root cause that triggered it.

Unfortunately I don't have  a core dump file because it was truncated for don't have space enough in file system. So I only have loggings filesin DEBUG level.

The proxy_1 apparently was processing a SUBSCRIBE request and the proxy_2 was processing a DMQ messages. Both of proxies crashed after appear this line in logging file
" CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 10"

What could trigger this error?

The loggin of proxy_1 is following:
