[JBoss JIRA] (MODCLUSTER-425) The timeout specified has expired: proxy: AJP: cping/cpong failed, ajp_ilink_receive() can't receive header
by Michal Babacek (JIRA)
[ https://issues.jboss.org/browse/MODCLUSTER-425?page=com.atlassian.jira.pl... ]
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.
