Description Ulrich Seidl 2007-10-19 07:47:37 EDT
Description of problem:
In RedHat ES 5, the xfs sometimes produces high cpu loads.

Version-Release number of selected component (if applicable):
xorg-x11-xfs 1.0.2

How reproducible:

Steps to Reproduce:
1. open a "wish"
2. enter "label .a -font {symbol 12} -text [ format %c 127 ]"
3. xfs now causes a high cpu load for some time. Can be checked e.g. with "top"
Actual results:
high cpu load after fontserver request

Expected results:
cpu load should not be higher as with RedHat ES 3 / 4 xfs.

I cannot reproduce it with xorg-x11-xfs-1.0.2-4 in kvm virtual RHEL5 machine
upgraded to the latest packages.

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.
