Strange problem with 4.9 new install

[Ralph M. Los]

...so I just installed a 4.9 server from the CDs I burned, no problems
during setup - but I've noticed strange things here and there that have
been 'not right'.  Processes stop (non-critical) for no reason, and
other things just aren't right...especially when I try to do a
'top'...this happens:

ralph@/stor>top
top: nlist failed
21:24:20

Can someone explain that?  I've googled to no avail - since it all talks
about re-compiling my kernel, which I'm not sure I even know how to do
yet...

Thoughts?  Thanks in advance
