David,
thanks for the reply.
Basically, it loops over the call to:
http://websvr:8080/timeline/WriteBadFeedToFileServlet
This servlet writes the url(of the bad feed) and a timestamp.
Needless to say, the servlet is called continuously and thus writing to a
log file each time.
Also, I never see the next line of code execute.
Thanks, Graham

Graham, when you say that line of code loops forever, you mean that you
keep seeing more and more HTTP POSTs either in FireBug or in your
server's logs? Or do you simply not see the next line of code executed?
