I am also having troubles with "db-issues (lost connection) occurred when accessing tools-db." from the webserver. I'm also getting "Could not connect to database: Can't connect to MySQL server on 'tools-db' " errors.
A few weeks ago, the database problems were only related to tools-webgrid-04. I just stopped and started the webserver to have it run on a different webgrid and things started running smoothly again. Not sure which webgrid is which, but when doing a qstat, it was running on the 2nd webgrid in the list. It is now running on the 4th.
