[Windows 2000] Is that Tomcat eating memory ?

["Oleg L. Sverdlov" <ol...@netmount.com>]

Hello.
The machine runs Tomcat 3.2.1 + jdk 1.3 + iis_redirect + Win2K Professional

Every time a browser reloads a page, "Java" process eats out a few bytes of memory.
Simple hello.jsp consumes a few bytes. Pages dealing with Java beans or db connections, consume more memory.

On Win2K Server,  I can see that memory pool of "Java" process does NOT grow, whereas "inetinfo" process eats out a few bytes of memory with every request.

In the same time, iis_redirect.log contains following entries:

[jk_isapi_plugin.c (261)]: jk_ws_service_t::start_response, ServerSupportFunction failed
[jk_ajp13_worker.c (314)]: Error ajp13_process_callback - start_response failed
[jk_isapi_plugin.c (554)]: HttpExtensionProc error, service() failed
[jk_isapi_plugin.c (355)]: jk_ws_service_t::write, WriteClient failed
[jk_ajp13_worker.c (325)]: Error ajp13_process_callback - write failed
[jk_isapi_plugin.c (554)]: HttpExtensionProc error, service() failed

Anybody know anything about this problem?
