Happens during the rebalancing-out of two nodes.
Reproduce: * Perform get/set operations continuously * Rebalance out two nodes poof! I was using multiple client handles for this test.. it seems each of them got that error. |

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 |

| This causes a complete application crash. |

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 |

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

| Merged Mark's code into our Enyim fork |
