I am receiving a strange error when running servlets to JSP's. I sometime
get the following message and sometimes the JSP just errors out. Any
suggestions or comments. Sometimes some of the images do not show up.

Technically this problem can occur at just about any WAS version 3.0 and beyond,
as it can occur in a timing window in the middle of a web app restart, which
happens automatically by updating a servlet class file. However I suspect you
are at v3.021 where due to a WebSphere bug, this problem struck more often.
There is an efix for v.3021 and should be fixed at later versions.
