I am trying to perform a standard install on my tomcat 5.5.27 server but I am getting deadlock errors. I have downloaded the war (2.1.8) and mapped it to /jforum

When I run the app at http://localhost:8080/jforum/install/install.jsp I get a deadlock

N.B. I have also tried to perform a manual install but I get the same results

I have attached the stacktrace

Help!!

The most likely cause of this is not using the correct JDBC driver for your version of MySQL. Eg., if you're using an older version of MySQL, you may need to downgrade the JDBC driver that comes with jForum.

I'm using mysql 5.1.24 and I see JForum uses mysql-connector 5.0.3 so I am assuming that this is ok?

You might upgrade to the latest JDBC driver. A quick google of "c3p0 deadlock mysql 5.1" came up with various MySQL issues about C3P0 and deadlocks. Most seem to be resolved with newer drivers.
