ifconfig -a, shows packets are being dropped. What is causing this?

I have a dedicated server somewhere and I just noticed that in 'ifconfig -a' shows me packets are being dropped. Any idea what is causing this? Because I do notice I lose connection to the server once awhile from several locations at the same time.

droping packets:

change the cable. this kind of errors is usually the cable, or the switch port (the switch not being able to process) or the land card damaged or with erroneous module loading it.
