Jerry Cwiklik reopened UIMA-5659: --------------------------------- Re-opening to change fixVersion from 2.2.0 to 2.2.2 > UIMA-DUCC: Agent JMX connection retry not working > ------------------------------------------------- > > Key: UIMA-5659 > URL: https://issues.apache.org/jira/browse/UIMA-5659 > Project: UIMA > Issue Type: Bug > Components: DUCC > Reporter: Jerry Cwiklik > Assignee: Jerry Cwiklik > Fix For: 2.2.0-Ducc > > > When an agent looses a JMX connection to a remote service it does not try to > recover it. Instead just reports 0's for GC values. > The problem is that it checks connection for null and only if true the > reconnect happens. In the failing scenario, the connection is established and > works for awhile than the connection fails due to a long GC in the service. > The connection object is stale (not null) at this point and reconnect does > not happen. > When a JMX failure occurs set the connection object to null forcing a > subsequent reconnect. When the JMX fails to fetch GC info the GC collection > should set GC values to -1. This info will be sent to Duccmon where the > failure can be visualized. Perhaps changing color of GC value to red could > alert a user. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
