Keith Wall reassigned QPID-7080:
--------------------------------
Assignee: Keith Wall (was: Alex Rudyy)
> MultiNodeTest#testQuorumOverride may fail sporadically
> ------------------------------------------------------
>
> Key: QPID-7080
> URL: https://issues.apache.org/jira/browse/QPID-7080
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker, Java Tests
> Reporter: Keith Wall
> Assignee: Keith Wall
> Priority: Minor
>
> Tes MultiNodeTest#testQuorumOverride is racey. The test verifies the
> behaviour of a group when all the replicas are killed and quorum override is
> applied to allow the master to continue in isolation.
> The test currently assumes that failover doesn't occur. This is wrong,
> failover may occur if the master discovers itself alone before the quorum
> override is applied. This discovery is asynchronous. The test cannot
> predict if failover will occur of not.
> In the unlucky case where failure occurs, the the failover happens whilst the
> test is committing a transaction. The transaction will correctly. The test
> does include code to retry failed transactions.
> Error Message
> Session exception occurred while trying to commit: sender for socket
