@gabriel: that's not really a KBFS crash. It looks like something on the device unmounted the FUSE mountpoint or removed the kernel extension, leaving KBFS with nothing to talk to. Maybe we should look into the system logs to figure out if anything happened in the kernel around then?

@strib @gabriel, here are the logs from around that time. I see a lot of entries for 'virusbarrierb' which I believe to be Panda Antivirus, my company's AV program. To debug, I disabled real-time scanning in Panda and the crashing seems to have stopped.
Can you provide a list of Mac directories that I should add to the AV whitelist?

(keybase.kbfs): This service is defined to be constantly running and is inherently inefficient.
Ouch, that's harsh.
Can you provide a list of Mac directories that I should add to the AV whitelist?
/keybase is the only mountpoint we add to your system, hopefully you can whitelist that and your problems will go away? If there's a way to whitelist processes too, I guess you should put "keybase.kbfs" (or just "kbfs") on there too.

This service is defined to be constantly running and is inherently inefficient. is shown in log for any launchd that has KeepAlive as true. You can pretty much ignore it.
Yeah, /keybase is the mountpoint and the kbfs process is /Applications/Keybase.app/Contents/SharedSupport/bin/kbfs.

@strib I wonder if we can fail more gracefully if AV software blocks something?
