Pavel Tupitsyn commented on IGNITE-27115:
-----------------------------------------
>From the log above we can see:
* "Old read-only tx" is initialized with a correct old timestamp
115700824823955457
* BUT when the lazy tx actually starts on the server, somehow it gets a newer
timestamp on the server: 115700824825987072 (while the client still thinks it
uses the old one - see "Tx started" log entry)
> .NET:
> Apache.Ignite.Tests.Transactions.TransactionsTests.TestReadOnlyTxSeesOldDataAfterUpdate(False)
> is still flaky
