[Freeswitch-users] FreeSWITCH - Segmentation fault in libcrypto.so.1.0.0

[Shaun Stokes]

Hi,

We use FreeSWITCH in a production enviroment and this morning experienced an outage caused by a segmentation fault (error 4 in libcrypto.so.1.0.0). Based on this error I'm geussing this is linked to the OpenSSL module? We have TLS disabled in all of our SIP profiles, how can we stop FreeSWITCH from using libcrypto, or is anyone able to advise on another method to fix this?

Our system:
Ubuntu 12.04 LTS
FreeSwitch 1.4.15
PostgreSQL 9.3.6
OpenSSL 1.0.1

Please see below for a copy of the kernal log, I've replaced server names and IP addresses with xxxx for security purposes.

Sep 19 00:21:13 xxxx kernel: [1276167.422451] show_signal_msg: 57 callbacks suppressed
Sep 19 00:21:13 xxxx kernel: [1276167.422456] freeswitch[53622]: segfault at 7f4590c6b000 ip 00007f45908fb6e3 sp 00007f453f50dfc0 error 4 in libcrypto.so.1.0.0[7f4590890000+1b2000]

This isn't the first time we've seen this error, but it has been many months since this last occured. The last time we expeirenced this type of segmentation fault (libcrypto) in FreeSWITCH we installed all available updates. On this occasion the segmentation fault happened overnight when we only have the occasional call. This happened approx 37 seconds after the last call had ended (see below).

There doesn't seem to be any connection with the time or any events on the server, there were no authentication attempts or logs that we can find which could be linked to segmentation fault.

Hope someone here can advise.

Many Thanks,
Shaun
