Some kind of network problem on the machine?

I think this could be a duplicate of adoptium/aqa-systemtest#246

[lumpfish]

This is different to the failures seen in adoptium/aqa-systemtest#246 (and similar issues) which was fixed by adoptium/aqa-systemtest#246.

As @pshipton suggests above there appears to be some issue with the test machine preventing the test processes connecting.

adoptium/infrastructure#1627 has been raised at AdoptOpenJDK.

[pshipton]

Since we have the issue raised at Adopt, I'll close this.
