[Freeswitch-users] significant delay waiting for response after playAndGetDigits()

[Wes]

I've narrowed it down a bit.  I think this may be a bug (memory leak maybe?)

It seems that the pagd function is very responsive on the first use, but 
on each repeated call to this function, it takes longer to respond to 
the user's keypress.

The following test script illustrates the problem.  It asks user to 
press a key, then it starts counting up to 10.  The first time, it stops 
right away after you press a key, telling you what key you pressed, the 
second time, it gets as far as the number 3, the third time, it counts 
up to six, and so on, until it completes the count all the way to 10, 
and then it says you've pressed an invalid entry, even though you indeed 
pressed a key at the beginning of the message.

lua script:

Could someone try this example on their own system to see if they could 
duplicate the behavior?

Thanks in advance!
