Tomcat error and strange behavior

[thisObject]

I started getting some issues with Tomcat recently. If you have an idea what might be happening and could share with me it would be grrrrrrrreat!

I have a servlet that is called from html page.

sometimes it goes through nicely but sometimes I get that deathTread error.

Another strange thing is that my servlet redirects to a some page lets say

http://www.somedomain/ABC/SSN/indexRedirect.jsp

so when servlet's code is executed it takes me to this location but tomcat give an error message:

HTTP Status 404 - /ABC/SSN/indexRedirect.jsp
type Status report
message /ABC/SSN/indexRedirect.jsp
description The requested resource (/ABC/SSN/indexRedirect.jsp is not available.
Apache Tomcat/5.5.9

I refresh the page and page is displayed with no problems.

This makes me think that my Tomcat has some issues.

Would you say reinstallation might/will solve all these issues that came up?

Thank you.
