Hi,
I am using following configuration:
Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
4GB RAM
Tomcat version 5.5
Java version "1.5.0_06"
. I am using CATALINA_OPTS "-Xms512m -Xmx512m -Djava.awt.headless=true" and
tomcat comes up fine and my http requests are processed normal.
If I change memory setting to 1024m (-Xmx1024m -Xms512m) then I
am getting this error:
java.lang.reflect.InvocationTargetException

... 6 more
And tomcat hangs and does not respond to http requests.
I am checking vmstat at this time and see 3GB free memory.
I would appreciate any help.
Thanks,
Rahul Tandon
