           Summary: Win32 Apache/jk/tomcat configuration causes 100% cpu
                    usage
           Product: Tomcat 5
           Version: 5.5.23
          Platform: Other
        OS/Version: Windows XP
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: javahollic@gmail.com


This has to be a major problem, mod-jk appears severely-broken on win32.

I installed apache 2.2, configured modjk, setup AJP13 to forward to
tomcat5.5.23/20 to say the /docs app on tomcat, so http://myhost/docs goes to
tomcat.

Ideally, the content would server and the cpu usage would drop to zero-ish. 
What I noticed is that the content serves up ok but then the TOMCAT process
sails up to 100%.  Kill the apache process and tomcat returns to normal. 
Restart apache and repeat with same results.

I found this on the 5.5.23 release, and verified on 5.5.20.  I tried to fiddle
with modjk but couldn't figure out how to load the modules in dll form.

Anyhow, I loaded up Tomcat6 and lo, the bug is gone.

This has taken me half a day to figure out, hopefully there is enough for y'all
to go on!
