I have the same problem on a FreeBSD 9.2 system and I never had the 
problem prior to 9.x.  I do have many other FreeBSD 9.2 systems where 
this doesn't happen, but those boxes are ssh access only with only 4 
admin users logging in whereas my problem box also permits telnet access 
and has maybe 10 or so logging in on a regular basis.  Up to now I had 
been thinking telnet was the culprit?
