[Asterisk-java-devel] Questions about connection timeouts

[Chris H. <ch...@as...>]

Hello All,
   We have built a fastagi that is designed to route a large amount  
of calls rather quickly and we are experiencing some timeouts on the  
Deadagi dialplan call.

timed out after MAX_AGI_CONNECT (2000) milliseconds

I know that I can up the timeout in the source and recompile but 2  
seconds is eons in call time.   I noticed about 10 of these in  a 15  
minute period with ~80 call coming into the system and my connection  
thread set to 100.  There should not have been any thread contention  
issues so I'm thinking a resource level issue.  Of course I'm running  
the AGI on my desktop running in debug mode inside of Eclipse so I  
guess this could be an issue.  I'll be testing tomorrow form a dual  
x86_64 AMD Opteron 250 so the issue may go away but I'm curious if  
anyone else has a issue with timeouts?

Cheers,
Chris

Imho even a desktop machine should be able to handle that load.
On my todo list is still some load testing. What I would like to do is
take some scripts that behave more or less like asterisk (regarding AGI
of course) with some configurable delay between the commands replies.
A bit like JMeter (maybe even a JMeter plugin?)

Anybody interested in helping?

This is close to  how we were testing.  We had one box originating  
calls to another system that would answer and send random DTMF to our  
fastagi that was doing get option calls.  We were sending 80 TDM  
calls between the systems every 30 seconds or so .  This is where the  
AGI timeout was happening.
