Subject Re: Pessimistic TXN did not release lock on a key, all subsequent txns failed

There are no something suspicious in stack trace.

You can check that key is locked using IgniteCache.isLocalLocked()
method. For remote nodes you can run task that performs this checking.

Could you please provide full logs for analysis?
