    InUseConnectionCount continously increasing...

    oguz.dag

      Hi,

      I am watching one of my connection pool (most used) using JMX-Console for a while... Eveything goes fine except InUseConnectionCount is increasing nearly by 1 per hour...

      I know it should be increased and decreased according to the usage of system... I can see that movement... But per hour the lower limit of InUseConnectionCount is increasing by 1... I mean graph goes upper and upper slowly (imagine x-axis time, y-axis InUseConnectionCount)... It should not be normal...

      Can Quartz cause this problem? coz I am using Quartz for my batch jobs... Can I see the details of this connections?

      Thank you...

          JBoss version?
          DB version?
          *-ds.xml file?
          log files/traces?

            There is no log file for this case, I was just watching the mbean...
