It wasn't just xlinux; I believe when I checked, the Windows job failed similarly.

I don't yet understand why these failed, there's plenty of space on the nodes and the master

Restarted 3 & 4, waiting for 1 & 2 to finish jobs then will restart them too. Please close, we can reopen if the issue recurs.

failed trying to create a shared cache. It seems there is a problem with the logic to fall back to smaller sizes. Can you please create another issue for this and investigate.

 [ERR] JVMSHRC561E Failed to initialize the shared classes cache, there is not enough space in the file system. Available free disk space bytes = 196653056, requested bytes = 314572800.

@AdamBrousseau I believe the machines have been fixed, and the cleaning job updated, I'll go ahead and close.
