[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-279) mod_cluster returns 503s after STATUS

mod_cluster returns 503s after STATUS ------------------------------------- Key: MODCLUSTER-279 URL: https://issues.jboss.org/browse/MODCLUSTER-279 Project: mod_cluster Issue Type: Bug Affects Versions: 1.2.0.Beta4 Environment: Fedora 15 Reporter: Radoslav Husar Assignee: Paul Ferraro Fix For: 1.2.1.Beta1 Attachments: logs-with-error.rar Simple use case -- client is going (no sessions) and no node is connected (so 404s). Then node starts up and 200 is expected, which happens but after short time on each STATUS message server returns 503s. {noformat} 127.0.0.1 - - [29/Jan/2012:14:34:30 +0530] "HEAD /load-demo/record HTTP/1.1" 404 -
