I have 3 repo configured,
- first one is proxied on external repo on the internet
- the second contains components developped by my company
- the third contains snapshot components of the internal component but is not
used at the moment
scan process is configured every minutes on each repo, all consumers are
activated.
I have a big problem a CPU occupation by archiva it is always at 99.9% and when
I configure process task at 5am for exemple the top command output
top - 10:31:40 up 3 days, 21:12, 2 users, load average: 0.05, 0.20, 0.76

So I think it is linked to the repo scan process task
I try to desactive all consumer but no effects are visible.
I try to reduce the scan frequency every 10 minutes but it is the same thing
I try to profile tomcat but i have some difficulties to analyse results.
