I am getting the following error on RT:
Database inaccessible; contact the RT administrator (email@example.com)
When checking the error log I see the following:
Nov 4 11:57:42 rt01 RT:  DBI connect('dbname=rt4;host=galera.company.local','rt',...) failed: Too many connections at /usr/local/share/perl5/DBIx/SearchBuilder/Handle.pm line 105.
This was working fine, I am using a galera cluster for my DB.
