It's been awhile since I dug into the scheduler.  I do remember the 2.4 
series being single-threaded.  I looked briefly at 3.2, and that one 
appears to run from a pool of threads, which should solve the problem 
you are seeing.  What are you running when the timer expires, an EJB or 
an MBean?  If the latter, you can start up another thread to do the 5 
minute processing, and return from the timer call immediately.  You're 
not supposed to start your own threads in an EJB, so if you are invoking 
  an EJB method from your timer, perhaps you can change that EJB method 
to invoke an MBean, and address as above.
