  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

MySQL Error during Backup

Medienpirat

New Pleskian
Hi

i got an error during daily backups within plesk from one database table:

Not all the data was backed up into...mysqldump: Got error: 23: Out of resources when opening file...
(Errcode: 24) when using LOCK TABLES

Does anyone have a solution?
 
I have add this but get the same message after next backup. Is there a way to add --single-transaction to mysqldump config?
 
Check output of following command:

# mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa -e "SHOW VARIABLES LIKE 'Open_files_limit';"

And increase open files limit in /etc/my.cnf with adding entry like

open_files_limit = 8196

After that restart mysql service and check limit with first command again.
