Hmmm. OK. I really have no idea what is going wrong in that case, so I will
be interested if you can come up with some more info.
By the way, for the list records, the SD does delete a few files such as spool
files, so it is theoretically possible it could delete a Volume, but that
seems to be nearly impossible, and if it did happen there would probably be
all kinds of other failures. Also in the development SVN for the next major
version, which I assume does not apply here, when a Volume is recycled (and
only during recycling), it is truncated, if the size of the file after
truncation is not zero (apparently NFS doesn't implement truncation), the SD
will delete the file, but it will then immediately re-create it and re-label
it, so even in that case the Volume should never be missing unless it is on
some mounted device as I mentioned in my previous email.
