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

[Ken Rice]

The only way to see what really caused this is with a proper backtrace(see:
https://freeswitch.org/confluence/display/FREESWITCH/Debugging#Debugging-Adv
ancedDebuggingTechniques )  and file a jira with all the details (see:

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

 

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).

switch_ivr_bridge.c:754 Hangup sofia/external/+xxxx at xxxx [CS_EXCHANGE_MEDIA]
[NORMAL_CLEARING]

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
