[jboss-user] [Installation, Configuration & DEPLOYMENT] - jboss tomcat issue ...?
Hi All,
We have a test environment with 2 apaches and clustered 4 Jboss instances .
We have setup load balancing via modjk properties in apache box.
Our setup is like each apache is in separate box and 2 Jboss instances in separate box.
[Totally 4 linux boxes]
During the peak load of users, we get lot of errors in modjk logs like as shown

ajp_send_request::jk_ajp_common.c (1359): (snode4) connecting to backend failed. Tomcat is
probably not started or is listening on the wrong port (errno=110)
|
|
I felt this may be due to insufficient threads dedicated to tomcat container to process
the requests from apache modjk to tomcat. But I am not sure whether this is correct or
not.
Please let me know if any one have encountered such errors ?
