[jira] [Commented] (UIMA-4690) DUCC service manager hangs when starting a service that has no available resoures

["Eddie Epstein (JIRA)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-4690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15258304#comment-15258304 ] 

Eddie Epstein commented on UIMA-4690:
-------------------------------------

Registered a service in a class with no resources. The service goes into state=starting on the service page, and on the service detail page shows state=WaitingForResources with Reason="Deferred because no hosts in class junk have sufficient memory to accomodate the request."

Meanwhile the SM continue to function normally, and subsequent ducc_service requests worked with no problem.

> When the SM starts a service in a scheduling_class that has no available resources it appears to hang waiting for the resource.  The WS gets no heartbeats and CLI requests such as query or unregister hang.
