I forgot to mention that the Tomcat service is launched using my credentials (not as local admin). The same account I use for a remote access and hence for launching the tomcat via startup.bat. I really do not see any differences. The same commands (cmd.exe, csript.exe, ...) are executed (64-bit variants) with the same params, but in one case there are memory limits. Btw, could be there any memory differences between users? I'll rather double check this. But I don't know how :-( What else... antivirus, firewall? I'll try to disable it for a while. AFAIK tomcat.exe is based on procrun wrapper. Is this wrapper memory safe? I just think (aloud) I could write a custom wrapper and execute my script directly from this new service... Quite complex to me... But I could check if it behaves differently or not...
