[rt-users] MySQL backups of RT 4.4.1 truncated (Cena, Stephen (ext. 300))

[Cena, Stephen (ext. 300)]

Small update: I was able to fix the system errors for logging. While the err.log doesn't contain much, there were two telling entries:

2017-01-26T01:12:29.975366Z 1622 [Note] Aborted connection 1622 to db: 'rt_service' user: 'backupdb' host: 'localhost' (Got an error writing communication packets)
2017-01-26T01:24:16.284038Z 1628 [Note] Aborted connection 1628 to db: 'rt_service' user: 'backupdb' host: 'localhost' (Got an error writing communication packets)

That's my MySQL backup account which only is used to dump the files and that's my affected database.

I've got an active MySQL 'support request' out there: https://forums.mysql.com/read.php?28,654543 , I'll be adding this shortly.

Something is definitely disrupting the connection.

Update on my MySQL backup issue: no change. I've now moved the Windows TEMP folders to the larger drive to see if the issue was running out of temp space and it has not helped. I will keep the group updated to any developments, but will refrain if its not anything noteworthy.  I'm going to try contacting the MySQL forums as this looks to be more suited to them. I'm also going to see if I can spin up a Linux MySQL DB server and "move" the tables into it via SFTP/copy, then attempt a backup there. I'm good with MySQL but it's not my bread & butter. Any additional help from the group will be welcomed.

To date, I've tried:
-Splitting the attachments table into its own backup job: failed.
-Moved MySQL temp folder/location to larger drive: failed.
-Moved Windows 2012 system TEMP folders to larger drive: failed.
-Ran MySQL diagnostics on the RT database affected: all tests pass
