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 occasio=
nal
errors in floating point calculations, resulting in a NaN, can occur in ran=
dom way
when using this kernel.  Upgrading to 2.2.14-12smp fixes the problem. The p=
roblem
may be related to occasional system crashes on heavily loaded systems runni=
ng
this version of the kernel reported on the RedHat website.  I would strongl=
y suggest
that anyone using 2.2.14-5.0smp upgrades to 2.2.14-12smp.  If you are runni=
ng
RedHat 6.2, and have not made any updates, you will be using 2.2.14-5.0.  I=
f you
have anymore questions about this, feel free to email me.
