Denis Magda commented on IGNITE-2343:
-------------------------------------
One more important thing to pay attention to while this issue will be being
fixed.
If the node fails with the stack trace from the description it doesn't respond
any longer and the only way to stop it is to kill forcibly using 'kill -9'.
