[Freeswitch-users] FreeSWITCH Stops Responding

It's an issue we've been searching for, if you uuid_kill it, and it says no
session, it only means the record was NOT removed from the sqlite database.

Nobody can seem to replicate the steps required to get into that condition,
maybe you could look thru the logs and see if you can replicate what ever
happened on that lingering UUID
