John, can you evaluate the severity of this? This has been a blocker for QE tests.

I've patched up Enyim a bit so that it no longer crashes -- the problem being some apparent reentrancy and race condition issues when a node is dying.

I'll file a gerrit patch when I figure out how to use this thing on my windows box

mark,

Just wondering if major is the right priority for this issue given that this happens during rebalancing
Do users tend to ignore one or two errors and are okay with retries for these type of errors
