[Fiware-creatifi-coaching] [CreatiFI Benelux Hub] Kurento, Firefox jsonrpc timeout kills nodejs app

[Andrea Maestrini]

Dear FIWARE coach,
we forward you a support request received from a CreatiFI applicant we are
not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.

************************

I'm working on getting Firefox to work (Chrome works fine). Sometimes I see
this exception only with Firefox. It occurs after the session is closed and
the recordings are being stopped. The recording fails (zero byte file). The
node app must be restarted after this. I dont see any errors in the kurento
server log - is there something I could look for?

thanks
Paul
