Yep ;)
You know, I think a much better idea for being in magic(5) would be
a check for lots of NULLs and calling the file "NULL data", rather than
MS Windows COFF Unknown CPU. This identification is a bug in the magic
file, really, since you can't call a short 0x any kind of magic
number!

Ah. In that case, next time it happens you need to make a copy of
the broken file and a copy of the good file and save them, so we
can look at the hexdumps.
If 'cp' does not copy the corrupted file, try using 'cat' to copy
it. 'cp' uses mmap. 'cat' does not.
There are still a few minor issues when mmap()ing NFS files, but
none that ought to effect the beginning of the file. We'll have
to figure out a way to reproduce the problem to really track it
down.

This has nothing to do with DOS. In case you didn't get my other hint:

Ok. This is something to watch, then. The corruption is worrysome. It is odd to get this sort of corruption in a client's buffer cache when all the file I/O is running over NFS. The real question is : where did the corruption come from? The client's IDE drive or something originally on the server? Are there any dos partitions on the server at all? If not, then the corruption is occuring on the client. But if the make procedure is not accessing (much of) the client's hard drive, where on the client could the corruption be coming from? -Matt Matthew Dillon To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
