Server has gone away (2006)

[imorandin]

Hi JetBackup Team,

I'm seeing a database backup failure on a cPanel server when JetBackup tries to export a large Moodle database.

Log excerpt:

Code: Select all

mysqldump: Error 2013: Lost connection to server during query when dumping table `mdl_logstore_standard_log` at row: 1183911
mysqldump: Couldn't execute ... Server has gone away (2006)

I already tried increasing **"Dump max allowed packet"** in JetBackup from **256M to 512M**, but the issue persists.

Relevant MySQL settings:

Code: Select all

max_allowed_packet=256M

net_write_timeout=300
net_read_timeout=300
wait_timeout=60

[mysqldump]
max_allowed_packet=513M

Thanks.

Hello imorandin,

Please try further increasing the Dump max allowed packet to 1GB in JetBackup's Performance Settings.

If the issue persists, I would recommend reaching out to our technical support team so that they can perform a deeper investigation. You can do so by emailing [email protected] or through your JetBackup Client Area.

Best Regards,
