Description Todd Clark 2000-10-28 03:13:04 UTC
This has happened twice now. The MySQL people told me to notify 
the developers of the problem:

Redhat 7.0 256mb ram pIII 750mhz

MySQL, being apparently the most stressed process on your system, 
was the one
that caused the kernel to panic. However, this is not the fault of 
MySQL - no
user process regardless of how buggy or malicious should ever be 
able to make
the kernel panic. You should send the above information to the kernel 
developers
- this will help them a great deal in fixing the bug.

Closing - this bug related to very old kernels and doesn't contain any
information thats useful for current bug engineering. Of course if mysql is
crashing on an RH8/9 setup and someone finds this bug - please open a new bug
