I have a question regarding the interaction between <min-pool-size/> and 
<idle-timeout-minutes/> properties. 

The JBossJCAPooling documentation says: 

anonymous wrote : Should closing idle connections cause the pool to fall below 
the min-pool-size, new/fresh connections are created.

Doesn't this create unnecessary churning of connections (out w/ idle in w/ 
new)? 

Here's my situation: 

I have these properties set at 10 for min-pool-size and 2 for 
idle-timeout-minutes. On average, I see 15 connections from each app server to 
the db server. 

This is what I'm seeing on my app servers: all db connections seem to get 
closed within about 5 minutes. New connections are created, about 4 per minute.

If I understand properly the MRU strategy used by the connection pool manager, 
then I do not understand why I am seeing this behavior.

Any help/thoughts would be greatly appreciated!

TIA,

Mike L. (aka patzerbud)
