Description:
Running mysqldump, program failed:
mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `tblName` at row: 20074 #### Status code 3 - aborting

MySQL error log attached.

How to repeat:
Rerun the backup that invokes mysqldump (cron job every 3 hours)

Other access to the database, including the apparently affected table, was not affected.

Problem seems to be fixed by restoring the complete database from a previous backup.

It is possible that the problem was triggerred by a task that generated a large number of updates (>10000) in one transaction, but since the issue did not become immediately apparent, it is difficult to be precise.
