HI All
I and running tomcat on HPUX machine. The problem is that on HP machine
the maximum thread per process allowed is 65 ( default), so i configured max
thread count in server.xml to 60. I used JMeter to check the behavior when
there is enough load on tomcat. What i have observed is that even though i
configured its maxthread count not to exceed 60 it is reaching 65 and as
soon as it goes beyond 65 tomcat throws OutOfMemoryError. After this the
thread are killed ( probably by the OS) and then the thread count comes back
to around 27 but tomcat does not process any new request any more. What i
was expecting is that once the threads are killed and thread count comes
back to 27 it should again start processing new request.

One option is that to increase the max thread per process limit of HP to
high value, but administrators are not very convinced with this idea

Any pointers on this issue.

Thanks and Regards
Pankaj Tiwari
