Jerry Cwiklik reopened UIMA-3605: --------------------------------- Assign Fix Version > UIMA-AS gets "Wire format negotiation timeout" on connection.open() > ------------------------------------------------------------------- > > Key: UIMA-3605 > URL: https://issues.apache.org/jira/browse/UIMA-3605 > Project: UIMA > Issue Type: Bug > Components: Async Scaleout > Affects Versions: 2.4.2AS > Reporter: Jerry Cwiklik > Assignee: Jerry Cwiklik > Fix For: 2.5.0AS > > > It appears that under heavy network load UIMA-AS is getting "Wire format > negotiation timeout" Exception when opening a connection to a broker. > The client side of AMQ is sending a frame containing its parameters to the > server (broker). It reconciles clients params against its own and sends a > reply back to the client. The reply apparently never reaches the client > causing the timer to pop (default=10secs) and an exception is thrown. > Attempt to extend the client timeout via > wireFormat.maxInactivityDurationInitalDelay=60000 doesnt fix the problem. One > possible explanation is that either the client wire format frame is not > reaching the server or the server's reply doesnt reach the client. This may > be due to a lost TCP packet. > Since the low level amq wire negotiation doesnt offer retry, the UIMA-AS may > need implement a higher level retry around the connection open() logic. It > should capture generic JMSException and check the associated description for > "wire format ..." problem. In such case, the connection should be closed and > reopened. -- This message was sent by Atlassian JIRA (v6.2#6252)
