Bruce Schuchardt commented on GEODE-2162:
-----------------------------------------
We really needed to know what the state of 10.118.32.97(6382)<v4>:32774 was.
It's odd that the output Hitesh put in his comment doesn't have the dunit VM of
origin in the log messages. When I run this test I see [vm_0], [vm+1], [vm_2]
etc at the beginning of each log statement. Nothing is run in the controller
VM so there's nothing logged by it.
I've run this test over 1000 times with various prods to make sure that the
member who takes over from the locator becomes the elder and lock grantor but
I've been unable to reproduce this hang, or even a reply-wait timeout. I added
hooks in Elder initialization code to make sure that the same scenario was
being run but it always worked as designed.
I'm closing this ticket. If it happens again we need a more thorough
collection of artifacts - at least the full log of the run including output
from all of the VMs.
