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:

Thank you.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.

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

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.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

Please help.
Thank you.
