>Description:
Mysql 4 crashes under load with FreeBSD 6.0.
Signal 6.
Started with dual P3, gmirror disks, custom SMP kernel.
Went to P4-2.8 with single ATA disk generic kernel.
Problem stays the same.
First tried build from source, went to ports version.
Problem stays the same. Message mentioning threads.
Finally went to FreeBSD 5.4 with the same machine and MySQL,
problem solved.

Combination FreeBSD 6 and Mysql 4 looks to be problematic.

>How-To-Repeat:
Just put some load on the mysql-server.

>Fix:
Use FreeBSD 5.4 instead of FreeBSD 6.0
