Here is a bug report in the format requested by linux/REPORTING-BUGS:
[1] page_alloc 2.4.1 kernel BUG running java 1.3.0
[2] Running java 1.3.0 e.g. 'java -jar SwingSet2.jar' etc. causes system
crashes and on other occasions, problems running other programs (e.g.
umount) subsequently. This does not happen every time but is likely
after ~30 minutes of runnning a java application.

The system is based on SuSE 7.0
[X] I have been suffering a lot of memory paging related Oops' on the
above PC since upgrading to the 2.2.16 kernel. Most of these problems
are fixed in 2.4.1 appart from the above. These problems don't appear
on a faster machine (e.g. P3 733MHz) so could be related to race
conditions? I appreciate that there is probably a bug in java 1.3.0 but
it would be nice if it didn't kill the whole machine!
Hope you can help! I would be glad to provide any more info that may
help.
regards,
Rob
