We have Jboss EAP 6.4 setup with moc_cluster and apache in front.
We frequently see these in apache error logs:
[error] proxy: CLUSTER: (balancer://abc). All workers are in error state for route (xyz)
(70014)End of file found: ajp_cping_cpong: apr_socket_recv failed
(120006)APR does not understand this error code: proxy: AJP: cping/cpong failed to
whenever these errors occur we don't see Jboss running out of threads. we have core threads at 150, when this error happens only 70 threads are active.
we have keep alive setting as 10 seonds in apache.
What could be causing these errors.
