00:12:19,603 ERROR [luci.lib.ricci_helpers] Unable to retrieve the batch number from virtsrv3n3
Looks like that comes from: ./usr/lib64/python2.6/site-packages/luci/lib/ricci_helpers.py
Whats unfortunate is their are several functions that emit that. I presume you could make them all unique if you actually don't know what the real issue is.
Why dont you pastebin a bigger chunk of that log?
