Unable to download remote agent jar on Bamboo 4.3

Hello,

On our bamboo 4.3 instance we get an error when we try to download the remote agent jar:

Caused by: com.atlassian.util.concurrent.LazyReference$InitializationException: java.io.FileNotFoundException: /tmp/jarClassPath9174692559081110970.jar (No such file or directory)

What could be going wrong here?

I managed to get around this by restarting bamboo. Could it be that that jar file is generated once and assumed to stay there forever? I can imagine that the tmp folder of an OS gets cleared from time to time which makes this approach a bit dangerous in my eyes. Could this be fixed by re-creating the jar when its not found?
