What does this mean?

     I have a AS 4100 with DG 4.0B, HSZ40 and advfs. Here is a message
     that appears once in a while:
     
     Apr 3 11:48:08 harrell vmunix: chk_bf_quota: group quota underflow
     for group 7 on fileset /
     
     
     What does it mean and should I be concerned about it? If you could
     direct me to the correct manual to fix it I would most appreciate it.
     
     Thanks,
     Bob
