Our webservers use arla to access the space they provide. A few days
ago I salvaged several volumes, and the process left hundreds of
__ORPHANFILE_.#*.#* in the root of the volumes involved. Since that
day, two of our webservers have started having arla fail. The two
machines involved are running NetBSD 2.0.2/i386, and both are now
running arla 0.43. They were running 0.37, previously, upgrading did
not change the results in this case, although it did dramatically
reduce the number of "nnpfs_send_message_wakeup_vmultiple" in syslog.
Any ideas why we have a one to one match of volumes with these files,
and volumes that cause arlad to exit (so far).
