Communications link failure

[susheel zaveri]

Hai

I am susheel, i am facing a strange problem (please help me out in solving this issue)

I am using tomcat 4, with MySql. I am using mysql/connector-j version 3.2.0 alpha..

My java classes are able to retrieve data from database, but suddenly after some time i get an error (Description from catalina.out is added below.). After which none of my classes can contact the database. But if i restart the server (tomcat) everything goes fine. i am unable to find the reason nor any specific patter. I shall be greatly indebted to you for any of your suggestion
