Network ports stop responding with inactivity

[mlinval]

We installed a 4510 a couple months ago and this past weekend there was a reported power surge on the floor.  Since then I have specialized printers and thin clients that will stop responding to pings after periods of inactivity.

If I disconnect the ethernet and plug it into a laptop the network is functioning.  When I look at the show interface it reports the interface is up and passing traffic.

If I keep a constant ping going to the ip address of one of these devices it will never drop.

Any ideas on what is going on?

here is an example of a port config:

interface GigabitEthernet7/47
 switchport access vlan 1862
 switchport mode access
 switchport voice vlan 1861
 switchport port-security maximum 8
 switchport port-security maximum 7 vlan access
 switchport port-security
 switchport port-security aging time 10
 switchport port-security violation restrict
 switchport port-security aging type inactivity
 load-interval 60
 storm-control action shutdown
 macro description HOST-DEFAULT
 spanning-tree portfast
 spanning-tree bpduguard enable
 ip dhcp snooping limit rate 50

I don't see anything in the config that would cause disconnects except

 "storm-control action shutdown" command

so, I would delete the command and watch the behavior again.

I have actually determined that if I remove the switchport port-security command the issue goes away.  Now to determine why that is happening.
