Servlet unavailable after restart

Hi all
I have a JSP/Servlet application that is working fine under Tomcat 4, except that if I restart the application (using an Ant task or the Tomcat Manager app) I will just get "Servlet MainServlet is currently unavailable" exceptions.
MainServlet is my controller servlet.
The only thing I can find in the logs are a number of exceptions, all the same, that I don't understand

A web search locates a few references to lifecycle errors, mainly in discussion forums, but I can't find a solution anywhere.
On my WinXP laptop implementation I can restart fine, with no problems. Same app, same config (as near as I can make out).

I just found a reference to a Tomcat hotfix for this issue.
That seems to fix the problem. I'll keep an eye on it and see what happens.
It is sorta covered in the JavaRanch Style Guide.
