First up I realise this may be more of a mysql issue than a strictly RT one, so apologies for that.
I’m trying to dump my rt3 database to restore into a new rt5 instance. The dump fails with
mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table
Attachments at row: 44697
after about 10 seconds. It’s exactly the same row number every time. After trying many different mysqldump incantations without success, I managed to track down the specific ticket number that it relates to - viewing that ticket in rt3 shows a bunch of errors instead of the content.
mysqlcheck --repair doesn’t work because it’s InnoDB, and most of the solutions I can find say to dump and restore, which is the exact thing I can’t do.
Can anyone suggest anything here? Is it feasible to create a new table and copy over to it? Or delete the offending record manually?
