Tomcat Error hangs Server

I have tomcat 4.1.29 server and jdk1.2 version installed on my server and using SQL-SERVER as database server. Recently i made some database driver updates and caused some issues and then rollback the driver. But after the update and rollback I found lot of strange issues raised on my server.

My CPU USAGE is 100% and MEM USAGE is very heavy, both are utilized by tomcat and SQL-SERVER and also i am getting the following error at my tomcat logs.

Could anyone guide me how can i overcome this issue.

Created catalinaLoader in: C:\Program Files\Apache\Tomcat 4.1\server\lib

You're using 1.2!!??? Sun killed that off a while ago. You're using a newer Tomcat - why so ancient of a JDK?

I would first upgrade to at least the 1.4.2 JDK's. I can't imagine that anyone would still be using a 1.2 JDK and would be able to assist you. 1.2 is not even officially supported under XP and above.

I agree. Here's the link:
