Hi there Lucee team,

I encountered errors and request timeouts while using the java concurrency framework (not pure threads)

Basically the following is done:

• ThreadPoolExecutor is created

• a task is submitted and the request completes normally

• the task runs fine (async in a created thread, just sleeping for 10s) and completes normally

• after the task is completed some time goes by (to be more specific the amount of time specified in the request timeout in the lucee admin)

• Errors show up in the requesttimeout.log as well as in the Console

Find a Mini-Test-Application attached. Just extract it somewhere in a folder beneath the webroot and call the index.cfm. Then watch the Console and requesttimeout.log.

I don't understand why the request timeout kicks in as the task is already completed. Even if the task itself running in a thread would take longer than the request timeout, the timeout should not be applied IMHO. And in the example neither the request that creates the thread pool nor the task that the thread runs takes longer than the request timeout.
It is obvious that the ThreadPoolExecutor might hold threads in a thread pool (for reuse). That' its job.

Did I do something wrong? Why does Lucee care about the threads in the pool and tries to stop them at all?

You can also try out Marc Esher's cfconcurrent framework and get the same results. Just try one or more of the sample apps that ship with the framework code. I don't think that this is intended behaviour.

Right now my workaround is to set the request timeout to a very high number in the request that creates the thread pool (and hope that the application is restarted before the timeout occurs). it might also help to set the request time out within the thread that is created. But this is only a workaround and I do not think that this should be necessary. As mentioned neither the request that creates the thread pool nor one of the single threads takes long processing time.

For reference, these are two forum topics as well as a cfconcurrent issue I created (actually I first saw the problem while using Marc's framework)

Help or a fix is much appreciated. And please keep up the excellent work!
