Manager Stability Features

Several precautions prevent Manager failure due to excessive traffic. For instance, the number of threads used for file update is limited. This prevents a large number of file updates from Brokers to Engines from preventing other HTTP activity due to use of all of the HTTP threads on the application server. Instead, Engines retry the download later when this maximum is reached. By default, this is set at 50 threads, but can be changed in the GridServer Administration Tool; go to Admin > System Admin > Manager Configuration > Communication, and change the Maximum Resource Download Connections property.

The number of Broker/Director messaging threads is also limited. If this limit is reached, clients retry rather than immediately fail.
