Timeout Manager

Timeout Manager is a non-distributed system for scheduling tasks for future execution in a background thread. A special Timeout object represents each task. If you want to reuse a particular thread, you can specify a timeout, after which the same thread can be reused. Timeout manager runs on both server and dispatcher nodes.

MaxPoolSize	Specifies the maximum size of the pool of Timeout objects.	1000
ChangePoolSizeStep	Specifies the step at which the pool size is changed.	50
InternalThreadPriority	Specifies the priority of a Timeout Manager thread.	5
ErrorLogFileName	Specifies the filename to which error log messages are written.	./managers/log /ERROR.log
CriticalLogLevel	Specifies the types of log messages have critical priority. It is a number from 0 to 7 specifying that log messages within [CriticalLogLevel,7] are written in the DefaultCriticalFile.	3

Critical Information and Troubleshooting Tips

The system administrator can change the size of the pool of Timeout objects. However, this requires more system memory resources. If the value of the InternalThreadPriority property is increased, the corresponding thread is of higher priority and therefore processes registered Timeout objects more accurately. This can increase system CPU usage time.
