DO NOT REPLY [Bug 47222] New: Changes made to ping_timeout via Status Worker not synced across Apache Children

https://issues.apache.org/bugzilla/show_bug.cgi?id=47222

           Summary: Changes made to ping_timeout via Status Worker not
                    synced across Apache Children
           Product: Tomcat Connectors
           Version: 1.2.28
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_jk
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: joe@k12s.phast.umass.edu


Changes made to ping_timeout via Status Worker not synced across Apache
Children

Configure Apache to use the mpm_worker, and start 2 children by default

Access the Status Worker, and change the "Ping Timeout:" on a worker.  EG:
Change it from 10000 to 15000

Query the status worker using a non-keepalived webbrowser (such as curl) and
see what the setting is set to.  It will alternate between the OLD setting and
the NEW setting.  EG:

curl "http://SERVERNAMEHERE/ajpstatus?cmd=show&w=WORKERNAMEHERE&mime=txt"
-> First request returned 10000 (the 'old' value)

curl "http://SERVERNAMEHERE/ajpstatus?cmd=show&w=WORKERNAMEHERE&mime=txt"
-> Second request returned 15000 (the 'new' value)

If you change another value, such as 'Retries', your change will by synced
across the children

This bug seems simple now, but it caused alot of head banging for me.  I didn't
realize that it was just this one parameter; I was assuming it was ALL
parameters that weren't being synced, and I kept looking for problems with my
Shm file.  It wasn't until I was writing this bug report I discovered it
appears (although I didn't throughly test) that it's just this one parameter
