[Spce-user] Rtpenginehardware sizing question

[John Nash]

I am running with log level = 2 and in /var/log/messages i do not see any
warning of kernel. I will try to run it again with higher log lel and see
what I get.
My OS is cent OS (Linux centos 2.6.32-573.7.1.el6.x86_64 ) My LAN card is
"Intel Corporation 82574L Gigabit Network Connection"

What other things I should check?
