    When and why does JBoss open more database connections than the maximum requested?

    Glauber Ribeiro Newbie

      I have a data source configured like this:




      In my interpretation, his should mean:

      • start with 25 connections
      • grow to 30 if needed
      • but not more than 30


      I have seen in several occasions the number of open connections go higher than 30. Some times i could correlate this with high activity, but not always. I've heard the number of connections went once to over 100 with no apparent provocation.


      Is this a known problem or feature? What triggers it?


      JBoss version: [4.3.0.GA_CP03 (build: SVNTag=JBPAPP_4_3_0_GA_CP03 date=200810241616)]


      Thank you for any help or ideas.
