Glauber Ribeiro [http://community.jboss.org/people/theglauber] created the discussion "When does JBoss shrink a connection pool?" To view the discussion, visit: http://community.jboss.org/message/569900#569900 -------------------------------------------------------------- I'm using JBoss 4.3 Say i have a data source defined like this:      <min-pool-size>5</min-pool-size>      <max-pool-size>25</max-pool-size>      <validate-on-match>false</validate-on-match>      <background-validation>true</background-validation>      <idle-timeout-minutes>5</idle-timeout-minutes>      <background-validation-minutes>1</background-validation-minutes>   <prefill>true</prefill>     <min-pool-size>5</min-pool-size>     <max-pool-size>25</max-pool-size>     <prefill>true</prefill> I see JBoss grab 5 connections when it starts, and grow to 25 as needed. But i'm not seeing it reliably shrink down back to 5. Is it supposed to? What triggers the shrinkage?
