All long running non js code should be wrapped in the suspend/resume
gc stuff. For example:
cb_state.ret = BOOLEAN_TO_JSVAL(JS_FALSE);
cb_state.saveDepth = JS_SuspendRequest(cx);
args.input_callback = dtmf_func;
args.buf = bp;
args.buflen = len;
switch_ivr_sleep(jss->session, ms, sync, &args);
JS_ResumeRequest(cx, cb_state.saveDepth);
I think this is your issue. Can you please file a bug on jira for
this issue (even better with a patch)

I've found the problem. one js thread wait in socket.read

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?

I've got a loop, but the first thing checked in each iteration is if
session.ready() returns false (and in that case exit the loop).
I do create sessions in the script: create, try to originate to a
destination and then finally bridge together the caller and the new
session.
I'll try to give you more details during the day.

do you have any loops in your code that might not check for
session.ready() in a exit when its not true.
The symptoms you posted would be consistent with held readlocks so
if you got a gcore (or windows equiv) of the process you might be
able to see what threads where doing what to hang on to the read lock.
also are you creating sessions in the script then executing app with
them, beware of this because the thread of the script is used to
execute apps on a session created that way and not the session thread.

Hello
I got problems with hanging spidermonkey sessions and need some
advice on how to debug them.
I've made a javascript queue application that uses
mod_spidermonkey_socket. It works fine for a while,
but after some calls I noticed that calls didnt get transferred to
agents. The reason was that earlier
calls had not been terminated properly.
freeswi...@test1> hupall
2009-01-15 12:15:04 [CRIT] switch_core_session.c:147
switch_core_session_hupall() Giving up with 8 sessions remaining
API CALL [hupall()] output:
+OK hangup all channels with cause MANAGER_REQUEST
freeswi...@test1> show calls
API CALL [show(calls)] output:
0 total.
As you can see, 8 sessions are alive, but none of them are listed as
calls. What kind of logs should I turn on to see what is happening
with those sessions?
Thanks,
Jonas
