[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-425) The timeout specified has expired: proxy: AJP: cping/cpong failed, ajp_ilink_receive() can't receive header

[Michal Babacek (JIRA)]

    [ https://issues.jboss.org/browse/MODCLUSTER-425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990367#comment-12990367 ] 

Michal Babacek commented on MODCLUSTER-425:
-------------------------------------------

 * ping setting: Does not help
 * ttl setting: Does not help
 * node-timeout: Does not help

Observation: It looks like there are ~2000 ESTABLISHED connections on AJP between the balancer and the worker node (one worker test). cping/cpong can't come through, consequently, worker is labelled as NOTOK.
