Dear DevConnect,

Please if you can document how many threads are configured when this parameter is set at value "0" (default) ??
Documentation does not explain the way it works.

Is it recommended to set in a value different from "0" ??
I've seen on previous questions related IC Connector that a value of 10 or 15 is being recommended.
This is a client with 150 max concurrent ivr AEP channels, but peaks at 100.
IVR application does about 3 IC Connector operations per call (newcall + 2 setvdu).

We are experiencing performance issued during peak times.
In the trace.log I can see messages saying "There is no available thread".
And in the same logs, only a max of 1 thread running: "There are 1 active threads currently in process".

thanks,
Eugenio R.

If set to 0 then the default of 3 is used.

If there is no available thread then the connector delays 250ms and retrys.

What is your current setting for the thread pool?

Why couñd be the reason that is shown in the logs that no more 1 thread is in use and then says that all threads are in use ??
Also, logs necer show more than 1 thread is in use, and requests have to
This is OD 6 sp 3

Thanks,
Eugenio

You did not answer the question above? Maybe you have it configured to 1 thread?

Sorry, didn't see your question.

It is set with the defaul, 0.

Try settingto 15 or 20 and see what happens. I believe you have to restart the server.

Ok, thanks. I will do so.

Eugenio
