Does NetBackup prohibit two restores to the same filesystem at the same
time?  (e.g. lock the space for exclusive use somehow?)

Background:
We were running an alternate path restore of 3 streams.   One of the
streams failed due to I/O error on read after restoring 10 files.
Using bpimmedia and bpflist I was able to determine all the files for
the failed stream and delete from the list the 10 that were successful.
I then started a bprestore using that list.

It gave the following log entries after mount and position:
15:35:11 (178059.001) INF - Beginning restore from server atucvd01 to
client atudvd01.
15:35:14 (178059.001) /database/proddata01/tx_datam08.dbf
15:35:14 (178059.001) Changed /database/proddata01/tx_datam08.dbf to
/database/conv2data/tx_datam08.dbf
15:35:36 (178059.001) Could only write 102912 of 262144 bytes to file
/database/conv2data/tx_datam08.dbf at file offset 100372992
15:35:36 (178059.001) Couldn't write to file
/database/conv2data/tx_datam08.dbf: No space left on device
15:35:36 (178059.001) Removing /database/conv2data/tx_datam08.dbf

The device is /database/conv2data and it was only 25% full at the time
this message occurred so is NOT out of space.   The file as you can see
is not that large.   The only thing I can think is that the original
restore (still running the other two streams) somehow has locked the
filesystem so that only it can restore to it.

If that isn't the case is there some other reason I would get such a no
space left message on a filesystem that is clearly not full?
