I have this issue also, but it seems my support have gone as far as they can with expediting the space in mysql. They referred myself back to mybb to figure out exactly what part of the software needs configuring in mysql.
We have tried a lot of methods from dropping in code to mysql to drop continuously open connections to refreshing the software, nothing has worked. It is not just a space issue, I have more than enough bandwidth and space, and after looking through the search engines for a fix it seems almost every host is referring back to mybb for the solution.
It would be great to get mybb's solution to this one so that all hosts can be notified as to exactly what the problem is, as I see mybb referring back to the host. So rather than keep running around in circles maybe a fix from mybb to hit our hosts with, or if a member has had this issue and fixed it let us all in on what the solution is.
The issue always refers back to mybb as it says contact mybb support, but those who have the issue always get referred to the host. My support team say that the software is third party so then mybb should have the solution... basically it is something within the mybb software configuration that is ripping the juice from the connections, but it is difficult to assess where it is.
My error is below... I cannot even find this file to split into rows or figure out the issue.
SQL Error:
2002 - Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Query:
[READ] Unable to connect to MySQL server
Someone must know the answer
:p
Thanks.
