Hi All,
Can somebody please help me out in stopping the surplus threads which
get created in tomcat 6.0 as we dont have "maxSpareThreads" attribute
anymore in it .. How can we close these threads
Thanks for ur help, Vicky
I've never noticed a lot of surplus threads when running Tomcat - even
when not using the Executor. Look at the actual number of threads
reported in the the "running thread" portion of Probe, or better yet
enable JMX and use VisualVM with the JMX plugin.
On a quiet Tomcat 6.0.35 running on Fedora 17 with jre 1.6.0_37 I see 22
threads (ps -FL [pid] | wc -l). This is with all of the examples loaded
. . . but I've not accessed that Tomcat so probably things are a bit
quieter than normal.
The real question running throughout all three of your threads now is
why are you so concerned about the number of threads.
The Executor will help balance some load on high traffic sites,
otherwise the private thread pools with appropriately tuned values
should work fine.
A note on "appropriately tuned values" - the defaults are usually quite
adequate for a large number of use cases. That's why they're the defaults.
So again, the real question is what perceived issue are you trying to
solve by being so concerned with the number of Connector - based threads?
. . . . just my two cents.
