Hello,
no longer need for debug messages, I know the reason now. Suspending a
'terminated' transaction exposes the risk of either crash or memory
leak. A transaction in this state has either a short life (few seconds)
or lives forever, because the transaction in terminated state can be
cleaned up by the wait timer, or if reference counter is incremented, is
unlikely to be decremented because no new branch transmission will be
done on a transaction that has a final response sent out. If you did the
processing very shortly after the sending of response, then you were
within the cleanup interval, but at any time can risk a crash, if there
is some delay in processing the async task.
Therefore, if the final response was sent out, the best is to send
needed data to another process via mqueue. The consumer processes of
mqueue task can be created with rtimer module. See sipweet slides in the
next presentation for a sample of mqueue+rtimer usage:

Hi,
Yes, i send final response before calling the method. The data
returned by SQL is processed by method to send new sip requests using
uac modules. I will send you debug level 3 logs shortly.
Thank you.

Hello,
was there a final response sent to the caller?
Can you run with debug=3 and send the log messages to me?
Cheers,
Daniel

Hi,
I have upgraded to Kamailio v4.3.3 rev. e275bc on my test server
running debian wheezy 32 bit and getting this error,
--
ERROR: async [async_sleep.c:248]: async_send_task(): failed to
suspend the processing
--
Basically, I am running a sql query in script which if returns
any records then i suspend the transaction with
"async_task_route" to process data returned by query later on.
The problem happens when this "async_task_route" method is
executed. This is old code which was working perfectly fine with
Kamailio v4.3.2 and it only gives error after the upgrade to v4.3.3.
Please help.
Thank you.
