I don't think that a debugger will help much in this case.

A profiler might help, if you can reproduce the error in a 
test environment. (see below) 

Some ideas:

- Use the access log to try to reproduce the error in a 
  test environment. (AFAIK apache jmeter has the ability 
  to create a test case from an access log) If you can
  reproduce the error, try to cut down the test case to
  the bare minimum that exposes the problem, then you 
  might have luck with a profiler.

- Write a servlet filter that logs the processing time 
  for each request.

- Extend the filter to interrupt the current thread 
  if it takes to long and dump some data.
