> When we increase load 300 calls to 500 calls , call will stuck around 50%.
> We have created a simple Dialplan like.
> [IVR]
> exten =>_X.,1,NoOp(IVR Start)
> exten =>_X.,n,Answer()
> exten =>_X.,n,Wait(1)
> exten =>_X.,n,Agi(ivr.php,1)
> I was added h extension but i tried with remove h extension as well.
> In my ivr.php File just have getting  channel variables and playing an audio file.Thats it.
> We have tested like send call via WINSIP dialer to load 500 call to specifc number and playing audio file vai AGI file.
> after couple of minutes, we hangup all calls from WINSIP Dialer Side,around 50% call drop correctly but remaining calls are stuck and showing last message like : Rx: BYE
> but channel showing still active.
> Also every 20 sec around getting below warning as well.
