log says nothing to me, can`t see what`s wrong..... could be something with hosting provider and running centOS on Virtuzzo ?
I know from my experience when You are running virtual machine on virtuzzo, there is something wired for example:
You cannot change the hostname
iptables goes crazy
You cannot adjust the clock time-date
what more could be god knows...
but any way here is the log output:
