[Freeswitch-users] FreeSWITCH mod_freetdm getting stuck

[DP Siddharth]

Hi,

Need help on issue we are facing with FreeSWITCH (FreeTDM endpoint). We
have following version of various components:

FreeSWITCH: Version 1.2.18 git 98c51ee
Wanpipe: 7.0.10
libsng_isdn: 7.29.0
Sangoma Card: A108 firmware v44
Host: Ubuntu 12.04 (3.11.0-13-generic)

Problem: FreeTDM endpoint stops working randomly, hence all the calls
running get stuck & no new call comes.

We start seeing lot of following logs:

So we are already in touch with Sangoma team & waiting for resolution, but
in case someone else has faced this issue & any suggestions to resolve it
will help.
