Hello,
I have tc 3.2.1 installed on w2k server with iis5, sun hotspot 2.0 server
mode and jdk 1.3. I have been running this implementation successfully for
the past several months with no problems. I decided to perform a stress
test to see how tc would handle it.
1. First test. 100 concurrent connections, each submitting a request to
/examples/jsp/forward.jsp every 10 seconds. This equated to 11 requests per
second. I ran this test for 24 hours. Results were perfect, no errors.
2. Second test. same test as above with 200 concurrent connections. This
equated to 18 requests per second. Ran for 5 minutes. This time I received
errors on 1% of the requests -- "500 - Internal Server Error". I checked
the Tomcat log and I am getting NullPointerExceptions from the jsp code
followed by an ArrayIndexOutOfBoundsException at
tomcat.util.SimplePool.put(SimplePool.java:112). The redirect dll reports a
few problems of not being able to handle the tc response. I suspect tc
could not deliver a response because of the internal errors. Not sure.
I go back to test 1 and everything is back to perfect. Go to test 2 again
and same errors. As I lowered the number of requests per second, it gets
better. It did not matter if I had 300 concurrent connections as long as
the request per second was around 11, everything worked fine. Does anyone
know what's up here?
Thanks
Mike
