GitHub user KuasarCloud added a comment to the discussion: Error after upgrading from ACS 4.15 to ACS 4.20
I solved it by changing some variables in the mariadb config file [mysqld] **table_definition_cache=4000 table_open_cache=8000** and in the shell **SET GLOBAL table_definition_cache = 4000; SET GLOBAL table_open_cache = 8000;** My config was too low **table_definition_cache=400 table_open_cache=2000** GitHub link: https://github.com/apache/cloudstack/discussions/10207#discussioncomment-11905426 ---- This is an automatically sent email for users@cloudstack.apache.org.
