I may help with own experience.
JSP Servlets will be removed from the threads if they aren't used some time.
your descriptions looks like you initialize something which on second
initialisation causes an error. So I think you have some variables in a <%!
%> tag which will be responsible for this.
'Response has already been committed' --> I use tomcat, this message appears
whenever the message was thrown into the System.out stream instead of the
response stream. If your JSP server has an own open window, check there for
the root exception.

Subject: why it could not find the servlet the second time around?
