Karl Wright commented on CONNECTORS-608:
----------------------------------------
Every ManifoldCF connection definition has a "Max connections" parameter. It
is on the "Throttling" tab.
You say you have about 10 "connections", but I think you mean you have 10
"connection definitions". If these are all talking to the same app server, the
SUM of all the max connections parameters of all the connections should not
exceed the number of app server threads.
