Advfs /usr partition full, but not really

Greetings,

I have a curious problem on our DU 4.0B system with patch 7.
The /usr partition, which is a 3GB advfs partition show something like

# df -k /usr
Filesystem 1024-blocks Used Available Capacity Mounted on
usr_domain#usr 3021760 1879517 46296 98% /usr

There are no other filesets in the usr_domain.

I have deleted hundreds of files from /usr, freeing up a few hundreds of megs
in the partition, but as soon as disk space is freed up, you see the available
disk space just start to disappear, and shortly the partition is full again.
The messages file does not report anything of interest, except that it says that
the partition is full. uerf does not have anything either.

I have been talking to Compaq support and the initial suggestion was to do a
vdump and vrestore, or add a volume to the domain. We don't really want to do
this unless our backs are against the wall. Support thinks that the problem may
be with the /usr/.tags/M-6 file:

# ls -l /usr/.tags/M-6
                        
---------- 0 root system 23085056 Dec 31 1969 /usr/.tags/M-6

which may have grown to a size that no longer permits the creation of more files
on the partition. But since I deleted numerous files, I would have expected
this to behaviour to change. It does not seem to be so.

Does anyone have any ideas on how this problem may be fixed, without using the
drastic methods suggested so far by Compaq Support?
