Thanks for the help it was a problem in /etc/host

had one to many localhost

was

127.0.0.1       localhost.localdomain   localhost ns1.acelaweb.com
64.55.96.10     ns1.acelaweb.com        ns1 # primary interface
64.55.96.9      ns2.acelaweb.com        ns2 # secondary interface

changed to

127.0.0.1       localhost.localdomain   localhost
64.55.96.10     ns1.acelaweb.com        ns1 # primary interface
64.55.96.9      ns2.acelaweb.com        ns2 # secondary interface
