[Freeswitch-users] Sometimes "hanging" channels

[Markus Bönke]

Hello All,

we are running freeswitch 1.6.20, calls are controlled via ESL, CDRs are written with mod_xml_cdrl. Sometimes we see „hanging“ channels. In such a case the CDR via mod_xml_cdr is written and the last log entry for such a call is "Locked, Waiting on external entities“.

...
How can I proceed to further analyze the problem ? In the last log line I also see the session number (Session 166111) - is there a way to find out on which external entity it is waiting?

Thanks and regards

Markus
