Queer behavior from Sunview console window

[Lyle Wiedeman]

Has anyone experienced this?

I have a Sun4 running 4.0 (it has a Sun3 diskless client running 4.0, but
this should be irrelevant).  Trying to launch sunview, I noticed that as
the console window was launched, it would hang and chew up 90% of the cpu
(the window itself was never drawn, but the "cmdtool -C" was visible in
ps(1)).  This was easily reproducible, and did not depend on who logged in
to launch sunview, nor how sunview was launched.  The cmdtool could be
killed, and a new console launched from within sunview, which would also
hang.  If the hung cmdtool were left running, and another console window
was launched, it would succeed, and the rogue could be killed without
harming the running console window.  The hung console window recovered
when an rlogin job which had seized ttyp0 logged off, but the console was
awarded ttyp3 .
