Hi All,

  We are using Glassfish 2.1.1 for a long time and is the server in
front-faced with Apache Httpserver. So we have done the modjk configurations
as mentioned and everything worked fine. Now we are in the process of
upgrading to Glassfish v3. We have done modjk configuration by running
following command:   create-network-listener --protocol http-listener-1
--listenerport 8009 --jkenabled true jk-connector   The worker.properties
has remain unchanged and we are using the same as used with Glassfish v2:  
worker.list=worker1 worker.worker1.port=8009 worker.worker1.host=localhost
worker.worker1.type=ajp13 worker.worker1.connection_pool_size=10   But now
we are intermittently getting the status 500 error. We are seeing following
exception in mod_jk. [Thu Feb 16 15:13:25 2012][16070:10] [warn]
jk_ajp_common.c (3185): Unable to get the free endpoint for worker worker1
from 10 slots   [Thu Feb 16 15:13:25 2012][16070:10] [error] mod_jk.c
(2612): Could not get endpoint for worker=worker1     My question is the
same setting works perfectly for Glassfish 2.1.1 in production environment
where the request load is considerably high where as in V3 we get this error
in stage environment while 2 users are using the app. What has changed in V3
related to mod_jk configuration? Is anything specific required to be tuned in
v3?   Please help   Regards Arnab
