Subject RES: Too many threads
Date Tue, 20 Aug 2002 12:30:38 GMT
Thanks for your atention Shapira, but I did search a lot in google for this
topics, but nobody seemed to have this kind of problem. I did read all
tomcat config docs, but the container seems to ignore my maxProcessors
parameter and starts lots of threads. I realy don't know what else to do.
I'm trying diferent connector at this time. I was using ajp 1.2, migrated to
1.3, and nothing, so I went to coyote and another deception, it stills
starts more threads than the parameter I set, it also happens to tomcats
examples, so the problem is not with my application otherwise it would not
happen to tomcats examples, I supose.
 Then again, thanks for your atention, hope you, or anobody else, can help
me with this, I'm running out of time,

 Ronaldo Florence

Hi,
The threading implementation of the JVM depends on the OS to some
extent.  Linux uses native threads as opposed to green or p threads, so
you see more processes at the OS-level.  You can google search for any
of the above terms and you'll find a ton of references.

For the tomcat configuration reference regarding acceptCount,
minProcessors, and maxProcessors, all of which affect the number of
threads used by tomcat, see:
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/http11.html
