|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 567973 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Thanks, this has helped. After doing your commands it crashed on a second table, but I was able to fix that with the same commands. The other affected table was this:
| PartTable | CREATE TABLE `parttable` ( |
`id` bigint(20) NOT NULL AUTO_INCREMENT, |
`pimItemId` bigint(20) NOT NULL, |
`partTypeId` bigint(20) NOT NULL, |
`data` longblob DEFAULT NULL, |
`datasize` bigint(20) NOT NULL, |
`version` int(11) DEFAULT 0, |
`storage` tinyint(4) DEFAULT 0, |
PRIMARY KEY (`id`), |
UNIQUE KEY `PartTable_pimItemIdTypeIndex` (`pimItemId`,`partTypeId`), |
KEY `PartTable_pimItemIdSortIndex` (`pimItemId`), |
KEY `PartTable_partTypeIndex` (`partTypeId`), |
CONSTRAINT `parttable_ibfk_1` FOREIGN KEY (`pimItemId`) REFERENCES `pimitemtable` (`id`) ON DELETE CASCADE ON UPDATE CASCADE, |
CONSTRAINT `parttable_ibfk_2` FOREIGN KEY (`partTypeId`) REFERENCES `parttypetable` (`id`) ON DELETE CASCADE ON UPDATE CASCADE |
) ENGINE=InnoDB AUTO_INCREMENT=295447 DEFAULT CHARSET=utf8 | |
While we could dismiss this bug as something that was caused by the known but irreproducible bug in the change buffer, the bug MDEV-29130 that you filed later may or may not be due to something else. Depending on the update and backup/restore history of the database, it might be explained by MDEV-24449.
Dakon, can you please try to clarify the history of the database?
- What was the first version of MySQL or MariaDB with which the database was created?
- Was Galera snapshot transfer ever used?
- Were data files ever restored from a physical backup (not logical, as in SQL dump)? If yes, how were the backups created? Backup tool name and version? File system snapshot?
I can't tell exactly when this database was created, but the oldest thing I found in the mysql.err.old is this:
2020-07-09 8:14:03 139992265905024 [Note] InnoDB: 5.7.30 started; log sequence number 222174628
|
I don't think Akonadi uses Galera for anything. The files were never restored from backup or similar, at most the LVM volume was moved from a different host.
Dakon, thank you. If crash recovery or xtrabackup or file system snapshot based copying was ever used on MySQL 5.7, this corruption could have been caused by the race condition that was fixed in MariaDB in MDEV-24449.
I think that MDEV-24449 could be the true cause of MySQL Bug #61104. That bug was never really fixed in MySQL, but only worked around.
Thank you for the report. Such errors often affect indexed virtual columns. I do not see any obvious use of indexed virtual columns in the table definition. If the PimItemTable_gidIndex were a UNIQUE key, it could use a virtual column (
MDEV-371).Thus, the most likely explanation would be an elusive bug in the InnoDB change buffer that we have been unable to reproduce, and thus analyze and fix. The change buffer was disabled by default some time ago in
MDEV-27734, but that will only prevent further writes via the change buffer. Rebuilding the secondary indexes (or the entire table) should help:I see that this server-crashing assertion was not replaced with some less intrusive error handling in
MDEV-13542. That could be done rather easily.
