Subject DO NOT REPLY [Bug 48830] New: IIS shutdown blocked in endpoint service when server doesn't respond
Date Mon, 01 Mar 2010 08:23:33 GMT

           Summary: IIS shutdown blocked in endpoint service when server
                    doesn't respond
           Product: Tomcat Connectors
           Version: 1.2.27
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: isapi

When the ISAPI redirector is used to access a back-end server that doesn't
respond to a request for a long time, IIS shutdown will be blocked.

The specific case I've observed this is an Eclipse RAP application, with UI
callbacks activated, which triggers a polling HTTP request to be made to the
server - this request only returns when there are UI updates to display

Debugging yields the stack trace below (note the line numbers will be a bit off
from trunk at the moment):

     isapi_redirect.dll!jk_tcp_socket_recvfull(unsigned int sd=1188, unsigned

(This is the call to e->service after obtaining a worker).

I've replicated this multiple times on shutdown with 1.2.30 and 1.2.27.

This is observed even after terminating the browser.
