[Freeswitch-users] spidermonkey problems

[Jonas Gauffin]

I've found the problem. one js thread wait in socket.read
(mod_spidermonkey_socket) on data.
That caller have hangup, which means that the garbage collector waits on it
to close.

All new javascript sessions waits in JS_AWAIT_GC_DONE for the garbage
collector to be done before proceeding (which means that all new javascript
calls don't do anything after being launched).

My server will not send anything until an agent gets free or the session
hangs up (detects it through the event socket). And the event socket will
not send that the session has been hangup until the socket have received
anything (and the script can exit). So it's kind of deadlock between my
server and the spidermonkey_socket.

Is it possible to add an option to socket.read to make it abort if the
session have been closed? I know that I wrote mod_spidermonkey_socket from
the start, but I can't figure out how to do it.

Will new sessions always wait on old ones to be garbage collected properly?
For instance, what happens if a script have a lenghty post process after
caller have hang up?
