Subject Re: Dealing with "Corrupt (negative) value length encountered"
Date Tue, 03 Jan 2012 20:15:16 GMT
I was able to scrub the node the repair that failed was running on. Are you
saying the error could be displayed on that node but the bad data coming
from another node ?

Log inspection also showed many of these, they seem to happen around when a
stream transfer finishes.
