Hi all,
I get a wired Exception thrown by a OJB application seems like something
deep out of the MySQL JDBC. Has anybody of you guys seen anything like that?
Anybody have a clue. I am using mysql connection 3.0.15. I share the library
across a set of web applications. The error only occures when the system
isn't answering any request for a while. Normally in the morning after not
beeing use during the night. After beeing thrown twice within 2 minutes,
everything looks fine.
Regards,
Nils
