Hi Smith B ,

What do you mean by 'parallel' here?

Are you referring to multi-instance loop (Activiti User Guide ) or parallel gateway (Activiti User Guide) ?

Thanks,

On startup, the engine will log the pool sizes as well as the keepalive time.

Let's make sure your settings have been picked up by checking for the log entries.
They should look something like:

09:31:07,320 [localhost-startStop-1] INFO org.activiti.engine.impl.asyncexecutor.DefaultAsyncJobExecutor - Creating thread pool queue of size 100
09:31:07,321 [localhost-startStop-1] INFO org.activiti.engine.impl.asyncexecutor.DefaultAsyncJobExecutor - Creating executor service with corePoolSize 2, maxPoolSize 10 and keepAliveTime 5000

Thanks,
greg

Thanks for the reply Greg and Thong.

We have verified the logs and it was picking up the configured properties. We have tried to use 5.22.0. But still facing same issue.

Creating executor service with corePoolSize 10, maxPoolSize 20

This doesnt appear to match the settings you posted earlier in your thread.

Are you sure the parameters are being picked up?

Hi Greg,

Even for corePoolSize 10 it is running only 8 jobs. Somehow I'm not able to figure out the issue. I have tried multiple machine and having the same issue.

Sorry for the late reply.

Probably not much more I can offer without a unit test, from your description you should be running up to max async jobs, but the devil is aleays in the detail, so a unit test is probably necessary at this point.
