Dolphin mysql Probleme

Hello,
my website on Plesk with Dolphin 7.3.3
has the following problem with the backup:

Does anyone have a advice?


Warning: mysql "kjddf558_1"
Not all the data was backed up into /var/lib/psa/dumps/domains/my-page.com/databases/kjddf558_1 successfully. Total space: 428624044032; Available space: 387420811264; Mounted on: /. mysqldump: Got error: 23: Out of resources when opening file './dolx29kk21/sys_profiles_match_mails.MYD' (Errcode: 24 - Too many open files) when using LOCK TABLES

 It is issue in server not with dolphin mysql.

many thanks have on server
found the error

In order to help anybody else with this kind of problem, the issue is that MySQL's open_files_limit needs to be raised. But this is a server issue and better suited for the MySQL or Plesk communities, or your host.
