Closed Issues in Silver Fabric 5.7.1 HF-1 (This Release)
================================================================================


FS-9365
Changed some usages of the internal default threadpool to use a Java
ExecutorService with a threadpool and a work queue to eliminate default pool
exhaustion that may occur when hundreds of stacks are being started and hundreds
of engines are logging in or logging off at the same time. 


Broker
FS-9372
Fixes an issue where a Stack already running in Manual Mode that is asked again
to run in Manual Mode with REST or an Ant script would stop and reallocate. The
fix is to ignore subsequent requests to run in Manual Mode once a Stack is
already running in Manual Mode. 


Load Balancing
FS-9371
When context-aware routing is configured to take precedence over a session
(SESSION_TAKES_PRECEDENCE_OVER_CONTEXT_AWARE_ROUTING=false), an Engine will be
chosen according to the context-aware routing statistic, even though a session
exists, when the request is for a tuple that is not currently loaded on any
Engine.
