Confluence is using MySQL database and may be exhibiting the following issue:

  1. Unexpected crashes
  2. Error messages in the Health Check menu:

The following error message appears in the atlassian-confluence.log

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-abc.supporthealthchecks' at line 1


Diagnostic Steps

Check if Confluence database has an illegal character hyphen "-" in it. 

From the example above, Confluence has been connected to a database with the name "confluence-abc"


The healthcheck plugin cannot handle a mysql database name with a hyphen in it.


Rename the database so that it does not contain hyphens "-"
