           Summary: mod_jk 1.2.10 status worker quick refresh problem
           Product: Tomcat 5
           Version: Unknown
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


I'm testing the load balancing worker. My setup is: 2 hosts running Debian Linux
(Sarge), Debian stock install of apache2. Apache2 using prefork workers.

I've got two such Linux boxes, my workers.properties is:

-------------------------------------------
worker.list=lb,status

worker.status.type=status

worker.node1.port=10900
worker.node1.host=rhubarb
worker.node1.type=ajp13
worker.node1.disabled=true

worker.node2.port=10900
worker.node2.host=blueberry
worker.node2.type=ajp13

worker.lb.balance_workers=node1,node2
worker.lb.type=lb
worker.lb.sticky_session=true
-------------------------------------------

My <VirtualHost> directive is:


-------------------------------------------
<VirtualHost *>
        ServerName martin.rhubarb.salad.taglab.com
        ServerAlias martin.rhubarb

        JKMount         /*           lb
        JKMount         /status      status
</VirtualHost>
------------------------------------------



I start doing some requests to "http://martin.rhubarb/test.jsp"; and it works
fine, the test jsp prints out the session id and some trace output in the log.
All requests keep going to the same host. All is fine.

-------------------------------------------
I look at the http://martin.rhubarb/status page and I can see:
node1   ajp13   rhubarb:10900   192.168.100.85:10900    Disabled        1       
1       0       0       0       0       0                
node2   ajp13   blueberry:10900 192.168.100.86:10900    OK      1       1       
15      0       7.1K    2.0K    0        
-------------------------------------------




If I refresh the /status page too quickly (click reload before the previous page
has loaded), the status can often get reset:

-------------------------------------------
node1   ajp13   rhubarb:10900   192.168.100.85:10900    Disabled        1       
1       0       0        0       0      0                
node2   ajp13   blueberry:10900 192.168.100.86:10900    OK      1       1       
0       0       0       0       0                
-------------------------------------------

Not only that, but sometimes it starts showing the "Disabled" and "OK" states
completely erratic reporting "Disabled" or "OK" on the wrong one. This looks
like a thread issue in the status worker since as far as I can tell the actual
lb worker continues to work fine.



Details of how I installed mod_jk.so:

I downloaded the source for the connectors 1.2.10. Compiled and installed it 
like.

$ cd jk/native
$ ./configure --with-apxs=/usr/bin/apxs2
$ make
$ cp apache-2.0/mod_jk.so /usr/lib/apache2/modules/
