> During state-transfer in tx cache, the node can receive {{CommitCommand}} from other node. After the node gets transaction data for affected segments, it creates the transaction with {{missingLookedUpEntries=true}} and the {{CommitCommand}} can be executed.
> In this command's {{perform(...)}} the transaction is *first* marked as completed, then it enters the interceptor chain. There, the {{PrepareCommand}} is created in {{StateTransferInterceptor.visitCommitCommand}} but after this is processed the {{TxInterceptor}} finds out that the transaction is already completed and executes {{RollbackCommand}}, clearing locks etc.
> Nevertheless, {{StateTransferInterceptor}} executes the initial {{CommitCommand}} afterwards. I suspect that this may be executed without the locks held.
> Anyway, it is not correct to execute both commit and rollback on the same transaction.
