To ease the maintenance of our Dutch National galaxy, we're trying to set up our own toolshed on a system that happens to have a nicely large MySQL database running. We'd like to make it use that database. The setup has been ok, until we started running the toolshed on the MySQL server for the first time, which resulted in the message in the community_webapp.log I copied below. Is this an incompatibility?
