Description:
A MySQL cluster set up on Fedora Core 4 with SELinux enabled crashes randomly over the period of a couple days.  Disabling SELinux completely repairs the problem.

How to repeat:
Enable SELinux on a Fedora Core 4 MySQL cluster.

Suggested fix:
Make it so it doesn't crash :-)

Forgot to set it to S2 (Serious).  Data is lost when it crashes.

Thank you for a bug report. 

If there was a crash, there should be something in the error logs. So, please, check and send the appropriate portions of the logs.

The description of you hardware and configuration parameters used will be useful too.

Please, try to check syslog results (dmesg) next time you'll see the crash. If SELinux is a reason, something should be written by kernel. (See http://bugs.mysql.com/bug.php?id=12676, for example.) It may give us some idea on what's happening.

I've run the NDB part of mysql-test-run on a rawhide box with SELinux enabled and not had any problems.

Could you please try running the test suite on an affected box and see if it fails?

cd mysql-test
./mysql-test-run --with-ndbcluster --do-test=ndb
