Hi,
since I've updated to 9.0.6, I have slowly response of myserver and a lot of errors in owncloud.log. This errors are new.

I have things like this :

n exception occurred while executing 'UPDATE oc_appconfig SET
configvalue = ? WHERE (appid = ?) AND (configkey = ?) AND
(configvalue <> ?)' with params ["510", "backgroundjob",
"lastjob", "510"]:
SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

and

Error PHP Error while sending QUERY packet. PID=42580 at
/var/www/html/owncloud/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php#91

or
whereas my sqld and apache are running well.

If anyone had a clue ? Or is there a way to revert back to the previous version ?

Thanks

Hi,

there is a part in the documentation how to resolve such "mysql server gone away" messages:

https://doc.owncloud.org/server/latest/admin_manual/configuration_database/linux_database_configuration.html#how-to-workaround-general-error-2006-mysql-server-has-gone-away

thanks realrancor for the link. The max_allowed_packet in my.cnf seems to be the faulty parameter.
Increasing it of 10% seems to do the trick.for the moment

I just don't understand the fact that it occurs just after the 9.0.6 update, this errors were not here last week. May be a coincidence with a higher usage of my server at the same moment, that's the magic of IT :slight_smile:
