Run away servlet in Tomcat

[Samuel Cheung <SC...@Novarra.com>]

Hi,

How does Tomcat handle a run away servlet? (I mean tomcat gets a request, it
call a servlet to handle it,  that servlet stuck in an infinite loop)

Can tomcat still handle new requests to same/other servlet?  Can we config
tomcat to kill certain request if it does not finish execution within a time
period?

Thank you.
Sam

Tomcat doesn't deal with this situation.

Sure, although ultimately the competition for CPU time is going to have
adverse effects on response time.

You'll have to arrange for that yourself, by starting a background
"watchdog timer" thread or something.  Tomcat doesn't have anything like
that -- it assumes that you've programmed your servlets correctly.
