We have upgraded a 0.8 cluster to 1.0.11. After upgrading the first node and running upgradesstables, we have run a routine repair operation, This operation has been running for a long time and does not seem to be progressing.

Running netstats has shown unexpected values for percentages as shown below. Any clue as to what could be be issue ?
