I have around 7 out of around 15 2940 that the management interface seems to hang.  Traffice still passes, but you can't ping the management IP nor can you ping from the switch.  All the interface are up up and even if I do a shut and no shut on the management interface (vlan 1) or on the gig uplink port, I still can't ping the management IP.  The only way I get this to work is to reboot the switch.  None of the ports goes into err disable so I don't know what is going on.  Can someone give me some advice on this.  Thanks.
