getting packet dropperd on interface

[Benjamin]

  Hi All,

In one of my server ,  i can see packet dropped on interface in ifconfig 
command.

I tried to find root cause of it, but nothing get any clue.

What could be the reason behind packet dropped occured.


ifconfig
em1       Link encap:Ethernet  HWaddr 00:25:90:39:70:0C
           inet addr:XX.XX.16.19  Bcast:XX.XX.16.255  Mask:255.255.255.0
