Subject out of memory exception for current AXIS version from CVS
Date Mon, 14 Jun 2004 03:00:45 GMT
hi,

there was some discussion abot memory problems and it seems i have a way 
to experiment and maybe find how to fix it (i did not see Peter 
Molettiere actually posting soemthing to JIRA on how to reproduce his 
problems? AFAICT only other open issues are 
http://nagoya.apache.org/jira/browse/AXIS-1270 
http://nagoya.apache.org/jira/browse/AXIS-1202 
http://nagoya.apache.org/jira/browse/AXIS-1095)

here is how to reproduce this OME (got it on linux but probably is the 
same on any OS) with the latest AXIS from CVS:

compile current axis and generate war file (ant war - wil take some time 
...)
get tomcat 4.1.30, deploy current axis.war, modify to disable multi-ref 
in WEB-INF\server-config.wsdd
set <parameter name="sendXsiTypes" value="false"/> and <parameter 
name="sendMultiRefs" value="false"/>

then download source code and compile from 
http://www.extreme.indiana.edu/~aslom/bnp/wsperf/axis_java/
<>
after service is deployed start tomcat (running JDK 1.4.2on linux 
without any chnages to -Xmx i.e. /opt/j2sdk/bin/java 
-Djava.endorsed.dirs=/home/aslom/Forge/tomcat/common/endorsed -classpath 
/opt/j2sdk/lib/tools.jar:/home/aslom/Forge/tomcat/bin/bootstrap.jar 
-Dcatalina.base=/home/aslom/Forge/tomcat 
-Dcatalina.home=/home/aslom/Forge/tomcat 
-Djava.io.tmpdir=/home/aslom/Forge/tomcat/temp 
org.apache.catalina.startup.Bootstrap start)

and run client with it:
java -Dmachine.name=LINUX_JDK142 -Dserver.name=AXIS_1_2 
soap_bench.BenchClient http://server:8080/axis/services/Benchmark1 
200000 ev 10,100,1000,5000,10000,25000,50000,75000,100000

the OME happens after running test two times, here are details:
