That module does 2 things.  First it handles the keepalives
if keep_alive_interval is > 0 in the pjsip.conf/global.  It also attempts
to mitigate DOS attacks if an attacker floods asterisk with TCP (or TLS)
connections but doesn't send any actual messages within the time set in
pjsip.conf/system/timer_b.   When a connection is opened, a timer is
started and if there is no recognizable SIP message before the timer
expires, you get the "Shutting down transport" message.

Yep, it was probably that network interruption.  The incoming messages were
being corrupted and not recognized as real SIP messages so the timer
expired and the transports were shut down.
