Hi All,
I am in appserver SQE team and I executed a list of tests using AS 9.1
EE build 28. Most of my tests restart an instance in a cluster(because
we test for failover and highavailability features of appserver). In the
course of execution, when the instance was restarted by one test, I
noticed "InstanceAlreadyExistsException" exception in DAS's server.log.
After that, the instance didnot get started completely. The stack trace
is attached below.
