HTTP code 500 when trying to access a artifact.

[Michael Delaney]

 All,
Our Archiva 1.1.2 server has started to act up a lot as of late. We're 
seeing some 500 error codes when trying to deply our artifacts. We're 
also seeing some behavior where an artifact is uploaded to Archiva (any 
type: pom, zip, jar, war; of varying size) but build freezes during the 
"upload" process. The newly updated file is accessible via WGET/HTTP 
calls but the build doesn't progress.

I assume this requires me to bump a logging value in log4j but I'm not 
sure which ones I should bump; or just brute force it and bump all of them.
