Mark actually i have a scenario in which my application receives variable amount of request depending on time . So at one point i have an approx around 400 users concurrently accessing my application as a result i have an approx 400 threads but when the request count decreases the thread count still remains 400 which eventually eat up my system resources. To cater to this situation i would like to know the option by which i can close my unused threads as maxSparethreads doesnt exist anymore in tomcat 6.0
Pls advise Thanks, Vicky On Nov 5, 2012, at 1:46 PM, Mark Eggers <its_toas...@yahoo.com> wrote: > On 11/4/2012 10:54 PM, vicky007aggar...@yahoo.co.in wrote: >> 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 ..
