Subject Apache will not start - "jk_lb_push::jk_lb_worker.c (347): syncing shm for lb '******' from mem (0->1)" after stopping apache.
Date Thu, 17 Nov 2011 14:02:38 GMT
I hope this is the correct forum to post questions like this. I am at a
wall and can't figure this out.
Hit an issue today with a PRD system while I was syncing up the platforms.
I was simply adding Apache rules in the httpd-vhost and httpd.conf files as
I have done many times and completed the same for DEV, STG. After stopping
apache and restarting it, it would not load.

Please note that it worked fine previously.

JBOSS instances through http load properly.
http://localhost:8009/app
http://localhost:8010/app

APACHE
Will not start,
Mod_jk.xxxx.log shows the following line
jk_lb_push::jk_lb_worker.c (347): syncing shm for lb 'loadbalancer' from
mem (0->1)
I cannot seem to get Apache and mod_jk to play nicely. I have since
restored the entire apache installation folder from before the failure.

The environment
       mod_jk-1.2.30.so (Also tried 1.2.32 compiled to no success)
       apache - 2.2.19
       jboss - eap-5.1
       RHEL - 4.8 Update 8


Here is the mod_jk.conf

       #mod_jk.conf
       # Where to find workers.properties
       JkWorkersFile conf/workers.properties

       #JkMountCopy all
       JkMountCopy On

       # Where to put jk logs
       JkLogFile /logs/apache/mod_jk.log

       # Set the jk log level [debug/warn/error/info]
       JkLogLevel debug

       # Select the log format
       JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

       # JkOptions indicates to send SSK KEY SIZE
       JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
+ForwardURIProxy

       # JkRequestLogFormat
       JkRequestLogFormat "%w %V %T"

       # Add shared memory.
       # This directive is present with 1.2.10 and
       # later versions fo mod_jk, and is needed for
       # load balancing to work properly
       JkShmFile /logs/apache/jk.shm

       # Add jkstatus for managing runtime data
       <Location /jkstatus/>
          JkMount status
          Order deny,allow
          #Deny from all
          Allow from all
       </Location>

Here is the worker.properties

#workers.properties

Apache never fully starts and it hangs at jk_lb_worker everytime.

Any ideas,
