       Body:
on windows you need to enable creation of more than 4000 ephemeral ports (windows by default
is not confgured for server like env), see:


How can I extend the range of ephemeral ports?
	Windows 2000, Windows XP, and Windows Server 2003, offer 3977 ephemeral ports by default.
	HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
	MaxUserPort Value Name, a REG_DWORD data type, and set the data value to a number in the
range of 5000 - 65534.
	HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
	TcpTimedWaitDelay Value Name, a REG_DWORD data type, and set the data value to a number of
seconds in the range of 30 - 300.
	
	
!!!! This setting won't take effect until your restart your computer. !!!!

        Key: AXIS-1391
    Summary: severe memory leakage in server side service (with tomcat)
       Type: Bug

     Status: Open
   Priority: Major

    Project: Axis
 Components: 
             Basic Architecture
   Versions:
             current (nightly)

Environment: Linux 2.4.24 debian (woody mostly)
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)


Description:
if you observe test progress on server machine using top you will notice that about every
10-20 seconds in-memory size of tomcat increases by 1MB ... probably the same would be happening
on windows or any other OS because of WORA ...

steps to reproduce

deploy test service (Benchmark1) available from
http://www.extreme.indiana.edu/~aslom/bnp/wsperf/

start tomcat with lot of memeory (to avoid too quick out of memory error):

setenv JAVA_OPTS -Xmx1024m
./catalina.sh start

run benchmark driver:

opt/j2sdk/bin/java -Dmachine.name=LINUX_JDK142 -Dserver.name=AXIS_1_2
soap_bench.BenchClient http://server:8080/axis/services/Benchmark1
200000 aa 10,100,1000,5000,10000,25000,50000,75000,100000

observe memory usage of tomcat process (on linux use top)


if memeory -Xmx is not increased you should get after some time (depending on default -Xmx)
this java.lang.OutOfMemoryError:
