Subject: CCL:Floating point errors with Redhat linux kernel 2.2.14-5.0smp

Dear CCLers,

I'd just like to warn anyone using RedHat Linux with kernel version
2.2.14-5.0smp
(the version which ships with RedHat 6.2).  We have discovered that
occasional
errors in floating point calculations, resulting in a NaN, can occur in
random way
when using this kernel.  Upgrading to 2.2.14-12smp fixes the problem.
The problem
may be related to occasional system crashes on heavily loaded systems
running
this version of the kernel reported on the RedHat website.  I would
strongly suggest
that anyone using 2.2.14-5.0smp upgrades to 2.2.14-12smp.  If you are
running
RedHat 6.2, and have not made any updates, you will be using
2.2.14-5.0.  If you
have anymore questions about this, feel free to email me.
