Hi Benjamin/Brett + Users, I've only been skimming this thread but am moving stuff across to archiva. i'm in a position to test on my setup something similar to what your doing to see if i get the same happening.
all i've read so far is db-artifacts and something scanning once a day. if i wanted to replicate the setup somewhat, what should i be looking at doing - i'm pretty green/new with archiva (got a snapshot repository with a few artifacts) if i can set up scheduled tasks to replicate whatever's going on, let me know, Cheers Chris On Sat, Feb 12, 2011 at 12:37 AM, Benjamin Knoth <kn...@mpdl.mpg.de> wrote: > Hi, > > I restarted on 11:06. > > On 11:56 i got this messages. > > 2011-02-11 11:56:05,101 [btpool0-6] INFO > org.codehaus.plexus.redback.struts2.in > terceptor.ForceAdminUserInterceptor - Admin user found.
