[rabbitmq-discuss] Hang on "starting database ...." remains in 2.8.2 cluster

Tue May 8 11:52:13 BST 2012

Hi Matt,

Predictably I can't reproduce this. Since you say that it'll happen 
"inevitably" (while if I understand correctly in your previous messages 
it was tricky to reproduce), can you send us more information about your 
setup and the steps on how to trigger the problem?

Francesco.
