> Key: OODT-203
> URL: https://issues.apache.org/jira/browse/OODT-203
> Project: OODT
> Issue Type: Sub-task
> Components: workflow manager
> Environment: from JPL's last internal WM JIRA release
> Reporter: David Woollard
> Assignee: Chris A. Mattmann
> Fix For: 0.5
>
>
> The current implementation of the threaded workflow engine uses a thread from
> its thread pool for each of the workflows it creates. This can cause a
> problem if a significant number of workflows submitted block waiting on
> preconditions to be satisfied. Each of these paused workflows hangs on to the
> thread allocated from the thread pool, so workflows that could be run are
> blocked by workflows waiting on preconditions if the thread pool is fully
> allocated.
