Subject Re: Connection leak

We recently had a similar problem.  Here's what we did, which appeared 
to alleviate the problem without addressing the underlying connection 

# don't wait indefinitely for a connection
torque.dsfactory.scimitar.pool.maxWait = 5000

# allow up to 25 connections in the pool (up from 8)
torque.dsfactory.scimitar.pool.maxActive = 25

# remove connections that have been abandoned
torque.dsfactory.scimitar.pool.removeAbandoned = true

This should postpone running out of connections by adding more and give 
the pool time to reclaim abandoned connections.  There is also a 
setting to have it track where connections are leaked from, at the 
expense of a little overhead when opening connections:

logAbandoned = true

More configuration settings are here:
