Goal

In some scenarios your projects might make an exhaustive use of the Engine threads and no matter how much you would increase the number of threads you will still see this warning:

"The Server is running out of automatic Execution Threads (100% of the pool is in use).
It is recommendable to expand the size through the Process Administrator."

The recommended maximum number of threads is, in reality, a fixed number and the maximum number of threads should not be increased too much above that value. For details on how to calculate this value, please, refer to http://www.oracle.com/technetwork/middleware/bpm/oraclebpmclusteringtips-132787.pdf

Therefore, if you are getting recurrent instances of this warning, you can reduce them by using the following set of JVM additional arguments:

fuego.server.automaticExecutionThreadsWarning
fuego.server.automaticExecutionThreadsSevere
fuego.server.gapBetweenLogs
