Cellsrv is hanging and RS restarting cellsrv RS-7445 [Serv CELLSRV hang detected]
* Every time cellsrv hungs, seconds before, there are messages related to NO IO COMPLETION, and always are FlashDisks.
* Iostat reports zero IO activity on all flashdisks. We would expect the device reported in the message having some large value on any of the attributes, but not.
* This system is a Full Rack X2-2 with half Expansion Rack X3-2.
* The cellsrv crash only happens on the X2-2 cells although we also have the report of the NO IO COMPLETION on the X3-2 cxells.
