problems with ps(1)

[Rick Wilhelm]

When I run ps(1) I get the following results

$ ps 
ps: unlink() failed
ps: /etc/ps_data, Permission denied
ps: Please notify your System Administrator
   PID TTY      TIME COMMAND
  6237 pts010   0:00 ksh
  6825 pts010   0:10 ps
$  

This problem happens sporadically, with no _apparent_ causes.
Anyone have any ideas?  I RTFM but to no avail.

System:  AT&T 6386 WGS running System V/386 Release 3.2
with KornShell Version 06/03/86a 386 Release 1.1

Thanks,

rick
