[Freeswitch-users] Problem with socket connection

[Lucas Ducculi]

Hi, I am using FreeSWITCH (version 1.10.2-release-14-f7bdd3845a ~ 64bit),
the system handles 30-70 simultaneous calls. On the other hand, we have an
IVR system that uses the node-esl library to connect to FreeSWITCH.

The problem we have is that some calls are dropped at different stages of
the IVR menu, and in the FS log we see the following.

In this case, a connection with the IVR was not established:

2021-12-15 13:31:43.332652 [DEBUG] sofia.c:7301 Channel sofia/external/
XXXXXXXXXX at sip.telnyx.com entering state [early][183]

2021-12-15 13:31:43.332652 [ERR] mod_event_socket.c:488 Socket Error!

In this other example I don't see an error with the socket in the log, but
the call cuts out just after reproducing this silence:

2021-12-14 21:20:08.732663 [DEBUG] switch_ivr_play_say.c:1933 done playing

Other example:

My impression is that the problem is related to the socket connection
between the IVR and FreeSWITCH. The two things are installed on the same
server (Linux Debian 10), any idea what could cause this problem?
