You will probably find that the Screen save has started in the screen with
the user logged in which does heaps of IO to the Xserver!

8555.3Sorry, not so easy.NETRIX::"[email protected]"Jarkko HietaniemiTue Jan 28 1997 10:024
Nothing so obvious I am afraid. This happens when the screen
saver most definitely is not on.

    Are you using the font server?  If so, has it been stopped for any
    reason?

8555.5Check fontpath for fontserverNETRIX::"[email protected]"Madeline T. AsmusWed Jan 29 1997 14:4225
Two possibilities. 

1. If you add a fontsever to the fontpath and then remove it,
(fp+ tcp/##.##.##.##:7100 ; fp- tcp/##.##.##.##) this will
cause the Xserver to consume 99% of the CPU very quickly.

2. If a fontserver is specified in the fontpath, and that 
fontserver disconnects once, the 99% CPU consumption occurs.

This turned out to be a bug direct from the XConsortium.
Specifically font rendering code no longer properly cleaned
up fontserver connections. 

A workaround is to comment out the font_renderer from the
server config file.  As root edit /var/X11/Xserver.conf
comment out this line. 

!        < fr_fs         libfr_fs.so     fs_register_fpe_functions >

or keep a watch out on the ups and downs of a referenced
fontserver.

Good Luck,
Madeline
