--- Comment #9 from Konstantin Kolinko <knst.koli...@gmail.com> --- 1. First, I should apologize for a quick rant. I guess that I reacted on "Can you help..." plea, as it is not something that I expect in a bug report. As I and Mark wrote previously, help is provided elsewhere. 2. This is still no a valid bug report for Tomcat, as the service wrapper is a third party component, provided by the Apache Commons Daemon project. See: https://tomcat.apache.org/bugreport.html#Third_party_components 3. Investigating further, my results are: TLDR, overall it seems like the -Xss option is ignored when launching Java via JNI API. Maybe Mark uses different version of Java. (1) I am able to reproduce the issue using the web application provided by the OP in comment 5, when using Apache Tomcat 9.0.68. I am using July 2022 versions of Java. E.g. 1.8.0u345 from Eclipse Adoptium. I have not updated to the October 2022 versions yet. Expected result: when I change the stack size, I expect the iteration numbers as printed in tomcat9-stdout.2022-10-27.log to change. Actual result: the numbers go up to around 15300, no more. (2) API used by Commons Daemon Procrun to launch JVM is JNI_CreateJavaVM. https://docs.oracle.com/javase/8/docs/technotes/guides/jni/spec/invocation.html#creating_the_vm In the source code the call is https://github.com/apache/commons-daemon/blob/master/src/native/windows/src/javajni.c#L817 As you can see the stack size is printed as a "-Xss" option for the command line: wsprintfA(iB[2], "-Xss%dk", dwSs); (3) If I enable "debug" log level on the "Logging" tab of the configuration dialog, I see the "-Xss" value being logged in commons-daemon.2022-10-27.log [2022-10-27 18:43:41] [debug] ( javajni.c:419 ) [11416] JNI_GetCreatedJavaVMs...
