I'm running Tomcat 5.0.28 on Windows XP Pro. I recently discovered that the number of
threads I could create from within my webapp was significantly less than I could running
a program with java.exe. After a lot of research, I discovered that if you run a JVM from
a C wrapper (as Tomcat does with procrun), the default stack size is taken from the
"stack reserve" field in the .exe header. Passing -Xss to the created JVM does
not appear to have any effect. Has anybody considered building Tomcat's procrun with a
smaller stack size, to make it more consistent with java.exe? In j2sdk 1.4.2_06 (I
haven't looked at other versions), java.exe is linked with a 256k stack. I would suggest
that would be a reasonable size for Tomcat as well.
I do not understand you question.
If it's how to set the stack size for the JVM, you can either use
manager gui or when install/update parameters use the
--JvmSs=NN that will be passed as -XssNNk
OTOH have no idea what would be the 'optimum' default stack size.
Also I'm not sure that java.exe itself sets the -Xss by itself unless
you explicitly pass that in command line.
