working directory is the "bin" directory

working directory means something like:
/TomcatServer/work/Catalina/localhost/webapp_name/ ?
because there is nothing there :( and there is enough free space.


There is also

-XX:HeapDumpPath=DIRECTORY_OR_FILE

(Caution: I don't know, if all JVM versions that implement
-XX:+HeapDumpOnOutOfMemoryError, implement this one too).

You should check in the process table (if it's a unix like system) if
your switches are picked up appropriately.

/usr/local/jdk/bin/java -server -Xms512m -Xmx1024m 
-XX:+HeapDumpOnOutOfMemoryError 
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager 
-Djava.endorsed.dirs=/usr/local/jakarta/jakarta-tomcat-5.5.9/common/endorsed 
-classpath 
:/usr/local/jakarta/jakarta-tomcat-5.5.9/bin/bootstrap.jar:/usr/local/jakarta/jakarta-tomcat-5.5.9/bin/commons-logging-api.jar
 -Dcatalina.base=/usr/local/jakarta/jakarta-tomcat-5.5.9 
-Dcatalina.home=/usr/local/jakarta/jakarta-tomcat-5.5.9 
-Djava.io.tmpdir=/usr/local/jakarta/jakarta-tomcat-5.5.9/temp 
org.apache.catalina.startup.Bootstrap start

is the process info. Any clue why it didn't get generated?

Also you can check their function by wrinting a simple java app, that
has an unterminated loop allocating objects and setting the heap size to
a small value, which should prodice an OurOfmemoryError and a heap dump.

I specified that parameter in JAVA_OPTS variable, but after the first 
"java.lang.OutOfMemoryError: Java heap space" error, no dump file was created. 
Where should that file be created by default? any clue?
Thanks
