Hi everyone:

  One of our DEC alpha suffered from endless forking. Here is a
description of the problem:

* DEC alpha 250 4/266, 64MB memory, running DU 3.2c

* vmstat reported only a few hunder free memory pages (8K each page)
right after the system is rebooted

* an average load of about 0.5, although no user program is running

* "monitor -magnify fork" reported about 16 forks/sec, and 641554 forks
since last night (!).

* lpd was the only processing running. After I de-queued the printer,
forking stopped right away, and system load droped to 0.00 .

  Is this a known problem with lpd on Digital Unix? Any fix?
  
  Thanks a lot;
