System: NetBSD 1.5X NetBSD 1.5X (EROS) #128: Mon Sep 3 22:24:52 EDT 2001 i386
Architecture: i386
Machine: i386
Creating/writing to a file on a filesystem mounted via the shlight program more
often than not causes the process doing the writing to hang and not respond to
kill -9, and freezes up all NFS activity, causing df, mount, and anything that
tries to access that filesystem to hang as well. The only way to recover from
this is to reboot, and three out of the four times this has happened, I ended up
having to drop into DDB and reboot with the sync command, since shutdown -r now
got as far as "syncing disks..." and stuck.

shlight //foo/share /mnt/foo
cd /mnt/foo
bonnie	(or try to create a tar archive, or use pax, those are the three i've
tried so far and all three hung it. ls works, FWIW)
