Apache will not start - "jk_lb_push::jk_lb_worker.c (347): syncing
shm for lb '******' from mem (0->1)" after stopping apache.
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

# Where to put jk logs

Apache never fully starts and it hangs at jk_lb_worker everytime.
Any ideas,

Correct forum is tomcat-users list
I mean you downloaded mod_jk from Tomcat so why Jakarta?
Anyhow, here is the link:
