>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Andrey Khitrin
>            Priority: Major
>              Labels: ignite-3
>             Fix For: 3.0.0-beta2

> How to reproduce:
> 1. Start a 1-node cluster
> 2. Create several simple tables (usually 5 is enough to reproduce):
> {code:sql}
> create table failoverTest00(k1 INTEGER not null, k2 INTEGER not null, v1 VARCHAR(100), v2 VARCHAR(255), v3 TIMESTAMP not null, primary key (k1, k2));
> create table failoverTest01(k1 INTEGER not null, k2 INTEGER not null, v1 VARCHAR(100), v2 VARCHAR(255), v3 TIMESTAMP not null, primary key (k1, k2));
> ...
> {code}
> 3. Fill every table with 1000 rows.
> 4. Ensure that every table contains 1000 rows:
> {code:sql}
> SELECT COUNT(*) FROM failoverTest00;
> ...
> {code}
> 5. Restart node (kill a Java process and start node again).
> 6. Check all tables again.
> Expected behavior: after restart, all tables still contains the same data as before.
> Actual behavior: for some tables, 1 or 2 rows may be missing, if we're fast enough on steps 3-4-5. Some contains 1000 rows, some contains 999 or 998.
> This bug was first observed only near Sep 15, 2023. Most probably, it was introduced somewhere near that date. Probably, it's an another face of IGNITE-20425 (I'm not sure though). No errors in logs observed.
