After consultation with UNIDATA and others on this list, I can 
definitively say that the problems I am seeing with Redhat 7.2 are not 
just me. It is, in fact, an operating system-wide problem that started 
with Redhat 7.1 and got worse with 7.2.

I have trouble tickets open with Redhat, so they know about it and are 
working on a solution. Interestingly, my single-CPU 
has been just fine. Maybe this primarily/only affects dual CPU machines? 
In any case, if you use as your primary, please fail 
over to until a fix can be found. Thank you and 
sorry for all the inconvenience.
