things like "rm" getting into the following backtrace:

==========================


The system, "waco.engr", has got into the wierd state,
where one rm is hung on XXX_grant_log_space(). Console
on telnet b30-3c-linux-annex 5002. Couple of "vi"
processes are also hung trying to access files on
/build1, the only xfs file system on the machine ...
Waco is running the alpha bits built as of last
saturday (09/02/00) ...

ananth.
