I'm running Lispworks 5.0.2 on Ubuntu 7.10, and am experiencing a
large number of hangs. This happens unpredictably while performing
ordinary operations in the editor such as pasting text or moving the
cursor. The CPU usage is split mainly between Xorg (~35%) and
lispworks (15-21%). Lispworks typically becomes completely
unresponsive, and occasionally returns to normal. I never experience
such problems with the Windows version, which is a paragon of
stability by comparison.
Has anyone else experienced this problem? Any idea what's causing it?

You are much more likely to get helpful answers on the LW mailing
list.

Is it reproducible?
Reproducibility comes in 4 flavors:
- same software causes same failure
(Try different versions of the program and of the operating system)
- same hardware causes same failure
(Try on another machine)
- same software circumstances (memory occupation, impossibility to
write to a device...) cause same failure
- same hardware circumstances (temperature, momentary electric high)
cause same failure
No Windows program can be a paragon of stability.
What does /var/log/syslog say?

I think it's a font-display problem of Motif on your Xorg environment,
not any bug of LispWorks itself.
I suggest you install a package named "xfs", and add following line
into /etc/X11/xorg.conf:
Fontpath "unix/:7100"
near other font-path config.
If you haven't install any "xfont-100dpi" or "xfonts-75dpi" package,
you should installed.
The key is, you MUST NOT let Xorg choose a True Type font to display
anything in Motif interface, that will be quite slow.

I don't know what's causing it but 35% for Xorg
seems rather a lot. Are you running demanding
graphics operations at the same time ? If not
then you might ask at an Ubuntu group/message
board. And why is lispworks using so much CPU
time ? Is it doing any calculations ?

I also has this problem with an earlier version of LW. The problem is
lesstif (which is the default motif installation on Ubuntu). To fix,
install
the libmotif3 package and then make the following modification to the
LW config file located in
/usr/local/lib/LispWorks/lib/4-3-0-0/config/use-motif-library
and make sure the preferred version is :motif (config command below)
(:detect-version (("/usr/X11R6/lib/libXm.so.2.0.1" :lesstif)
("/usr/X11R6/lib/libXm.so.3" :motif))
:prefer-version :motif
)

It's a problem with Motif, according to the answer I got from lispworks when
I reported it.
It happens to me under Mandriva linux, also.
The operation that seems to cause the problem for me is copy-paste from a
non-lispworks window to a lispworks window. You can try hitting the
buttons in the lispworks monitor ('break to tty', 'interrupt'), I can't
remember if that works for me. I have learned to avoid pasting from other
windows and use intermediate files in the few cases where I do need to grab
something from elsewhere.
