local client 1.8.2-1ubuntu0.1 keeps disappearing files

[Dorian Taylor]

Unfortunately this is not the best bug report I've written, but given the circumstances it's the best I can do:

• OpenAFS client is on the same machine as the server
• During normal operation, files and directories disappear
• Show up in `ls -l` eg `?????????? ? ? ? ? ? user`
• Assume this is a client problem because other clients on the network can see the files
• Stopping and restarting client and server do not restore the files
• `bos salvage` and/or `fs setca -1` by the administrator account *sometimes* seem to fix the problem but other times do not
• This is a random, intermittent problem so I do not know of a reliable way to replicate.

Once again, this is 1.8.2-1ubuntu0.1 on amd64, kernel 5.0.0-21-generic #22-Ubuntu SMP on 19.04.
