Unable to create lock

Once in a while mail to the archive is refuse with error
"ERROR: Unable to create /path/.mhonarc.lck after 20 tries"

I have increased both times between tries and the number of tries with
  -lockdelay 15 -locktries 20

The machine is quite busy. Has any one tried any other solutions such as
always "exit 75" (temporay failure) if locking fails?
