Cisco Switching/Routing :: WS-C3560-24PS / WS-C3560-48PS - Port With WAP Goes To Err-disable?

We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
 
Here's the info:
 
Model: cisco WS-C3560-24PS and cisco WS-C3560-48PS
Image:c3560-ipbase-mz.122-35.SE5.bin
 
This is the log from one switch:

31w5d: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/2, putting Fa0/2 in err-disable state
31w5d: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 74e2.f592.f7f2 on port FastEthernet0/2.
31w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed  state to down
 
And from another, which is almost the same:

5d10h: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/3, putting Fa0/3 in err-disable state
5d10h: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address d8a2.5e31.2cf6 on port FastEthernet0/3.
5d10h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/3, changed state to down
5d10h: %LINK-3-UPDOWN: Interface FastEthernet0/3, changed state to down
 
Here's the configuration of fe interfaces (they are all alike):

interface FastEthernet0/2
description Voice & Data Combo Port
switchport access vlan 11
switchport mode access
switchport voice vlan 15
