Cpu usage 100%

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.
