mod_webapp hangs when page is hit before the first page is finished loading

           Summary: mod_webapp hangs when page is hit before the first page
                    is finished loading
           Product: Tomcat 4
           Version: 4.0.2 Final
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Webapp Connector
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: j27lee@yahoo.com


Running Apache 1.3.22, Tomcat 4.0.2, Win2K SP2

When I first access the page, It loads fairly slowly, and not all images show 
up all the time.  If I click refresh, or if somebody else goes to that page 
before my page is finished, whoever hits the site second gets: 

WebApp: Error 500
(File: pr_warp.c Line: 438) 
Invalid packet 16 

Both Apache and Tomcat are still running at this point.  All subsequent hits 
return the same error until Both Apache and Tomcat are restarted.

Here are the error logs:

This sometimes causes Apache to crash, generating errors:

 [error] Connection "conn" cannot connect
 [error] Cannot open connection conn
 [error] Cannot shutdown "conn"
 [error] Cannot shutdown "conn"


Is this related to bug 3509 or 4793?
