      Description

      we use Archiva and we have problems with our cpu usage.
      If i restart archiva everything is running fine. After 3-6 hours the
      java process of archiva use 100% of the cpu from one to the next
      moment. We had this problem on Archiva 1.3.1 and 1.3.3. On Archiva
      1.3.1 it came after the 3-5 times where the db artefacts were updated.
      The snapshot repository need 12 minutes. I deleted some snapshots.
      Lasst week we updated it to 1.3.3 and now i can't find something
      important on log. On the last 100% usage problem i got a message from
      nagios the usage of cpu is critcal at 7:43 o'clock, but in the log i
      found only this messages.

      At the moment archiva 1.3.4 is installed.
