Hi folks!

After upgrading to MariaDB (instead of MySQL) I get this error.

Error while backing up database XXX
Error while backing up database XXX: The sql file is 0 bytes in size: /home/tmp/admin.933/admin/backup/XXX.sql
mysqldump error output: /usr/bin/mysqldump: unknown variable 'max_connections=5000'


What's the best way to fix this?

Cheers!
 
It's pretty empty...

Code: 
#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

max_connections=5000
 
Hello,

Move

Code: 
 max_connections=5000

under section

Code: 
[mysqld]

in /etc/my.cnf


Code: 
#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]

#
# include all files from the config directory
#

!includedir /etc/my.cnf.d

[mysqld]
max_connections=5000
 
Directadmin does not add anything of that in MySQL config.

I will need root access to SSH on your server to investigate the incident if you want to know how it happened. It will cost you some money.
 
when I backup the accounts i give this error:
Error while backing up database SQL file is 0 bytes in size

my.cnf contents:

maybe this makes bad impact:
innodb_strict_mode = 'OFF'
sql_mode=""
 
I wanted to add to this,

I updated DA via CustomBuild and also MariaDB to 10.4.20. I noticed at the end of the log, a similar message:

Again, please don't post in 2 threads and go over to the other one. Also for people helping you it's confusing working in two threads.
