Exception when AKKA cluster haven't setup

[Dai Yinhua]

Hi,

I was running a akka cluster, but when I start only one instance of the akka application, then it will throw below exception repeatedly, can you help to explain what is the issue and how to avoid it.

Any suggestion please?

[Patrik Nordwall]

Can you reproduce it outside Eclipse? Do you block any threads when debugging?

Try with latest Akka version 2.4.16. I know there has been problems with deleting such files on windows in some previous Aeron versions, but they should be fixed in latest. Make sure that you regenerate the Eclipse projects so that you are not using an old version of Akka or Aeron in Eclipse.

Hi Patrik,

Yes, it can be reproduced outside of Eclipse in Windows.
