I don't know if this has something to do with your environment, but i noticed that (under solaris) the old mysql driver was not working good with jdk 1.3.1. After upgrading to the new jdbc driver the problems were solved.
I'm investigating a regular crash of a mmbase (1.6.0) installation... one of the candidates of the problems is the mysql jdbc driver. Currently it's using an older mysql driver (mm.mysql-2.0.12-bin.jar), because I was having trouble with getting mmbase to run properly with more recent versions. Did anybody manage to get mmbase to run with a more recent version of mysql jdbc (or by the more fancy name "Connector/J")
good luck, Rob
