AdvFS fileset soft limit automatically set

Hi Gurus,

Hopefully someone can re-assure me this is not a bug and merely a *product
feature*...

Running Tru64 v4.0F PK8 and I have an AdvFS file domain with an LSM volume
as its disk. I have created AdvFS filesets from this file domain which
appears as:

# df -k
Filesystem 1024-blocks Used Available Capacity Mounted on
...
db3_domain#db3 4089520 3595696 493824 88% /db3
db3_domain#local 8880632 116487 5160384 3% /usr/local
...
#

Notice the 1024-blocks for db3_domain#db3? This was previously 8880632 but
after restoring a large amount of data from tape somehow the total size then
drops to 4089520. I later found that the cause was an AdvFS fileset soft
limit which was somehow automagically sets while copying large files.

Resetting the softlimit to 'unlimited' as follows solved the problem:
# chfsets -B 0 -b 0 db3_domain db3
db3
        Id : 371e163d.000615f5.3.8003
        Block H Limit: 0 --> 0
        Block S Limit: 4089520 --> 0
# df -k
Filesystem 1024-blocks Used Available Capacity Mounted on
...
db3_domain#db3 8880632 3595696 5160384 42% /db3
db3_domain#local 8880632 116487 5160384 3% /usr/local
...

My query is simply whether this behaviour is an built-in feature to AdvFS?
Perhaps to prevent some malicious user from totally filling up the domain?

Thanks in advance.

Regards,
Bobby Mackun
