TokuDB crashes

[akrus]

Hello!

This bug was already reported to MariaDB:
https://jira.mariadb.org/browse/MDEV-11143

As Percona is upstream, reporting here as well.

Logs are attached.

Both times this happened when daily repartitioning event was running.

Here are the logs from repartitioning script (db and table names changed):

DO localhost alter table `database1`.`table1` drop partition p20161011;
[ERR]: localhost Can't execute SQL statement: alter table `database1`.`table1` drop partition p20161011; on DB database1 : Lost connection to MySQL server during query
READY localhost alter table `database1`.`table1` drop partition p20161011;
DO localhost alter table `database1`.`table1` reorganize partition pmax into (partition p20161117 VALUES LESS THAN(1479420000),PARTITION pmax VALUES LESS THAN MAXVALUE ENGINE = TokuDB);
[ERR]: localhost Can't execute SQL statement: alter table `database1`.`table1` reorganize partition pmax into (partition p20161117 VALUES LESS THAN(1479420000),PARTITION pmax VALUES LESS THAN MAXVALUE ENGINE = TokuDB); on DB database1 : MySQL server has gone away
READY localhost alter table `database1`.`table1` reorganize partition pmax into (partition p20161117 VALUES LESS THAN(1479420000),PARTITION pmax VALUES LESS THAN MAXVALUE ENGINE = TokuDB);

Tracking in https://jira.percona.com/browse/TDB-49, please login there to Percona JIRA and 'watch' for future updates. Marking it as opinion here as there is no other accurate matching state.
