You could try switching to a soft mount. This can cause silent data
loss when a server goes down, but I don't think that should be an issue
if this is a read-only mount. Just add "soft" to the mount options. (I
haven't tried soft-mounting for this particular case, so I don't know
for sure that it will help)
