Description Need Real Name 2000-10-09 09:11:14 EDT
Running screen-3.9.4-3 or screen-3.9.5-4 utilizes 95-99% of CPU.
Comment 1 Crutcher Dunnavant 2000-10-10 16:35:55 EDT
Could you give me more info, I can't reproduce.

A good test case would be nice.
Comment 2 Need Real Name 2000-10-11 08:25:10 EDT
Relevant packages:

screen-3.9.4-3
ncurses-4.2-25
utempter-0.5.1-2
glibc-2.1.2-11
kernel-2.2.12-20

Works fine on an IBM ThinkPad 240 (Celeron 300Mhz).

Eats up 99% of CPU time on a SCSI-based, Pentium III 600MHz workstation.

I can provide strace output of both on request.
Comment 3 Crutcher Dunnavant 2000-10-19 11:35:08 EDT
Please, give me some straces then.

*sigh*
Screen is pretty much broke by design,
but it's the only thing that does what it does.
