MemGuard hit

[mritter0]

Beta 9. Booted into my OS4.1FE system. Didn't do anything. After a few minutes I got this in Sashimi:

I don't know what it means. Didn't crash system. I have gotten this a few times, totally random. Just letting you know.

I think this has been reported previously. Error happens inside dos/MakeDosNode() dos.library function. There is nothing I can do.

EDIT: you probably have automount removable drives enabled and something was on the fly inserted.
