J9729A port going offine with Cisco APs attached

I have a procurve J9729A that has about five Cisco Air-Lap1142n APs connected. When I had to replace a couple of them they will stay up for about a couple of days and then go down for no apparent reason. When I check the switch logs I can track when the port goes offline. Link indicator shows no link and the AP is stil powered. Cabling is verified and good. Is there a way to force a port to stay on-line? I also checked POE settings and the switch is only using half it's 370 watts.

Hi!

Are you able to post outputs of

show power-over-ethernet <port-id or port-ids-range or port-ids-list>

 CLI command?

Which software version is running on your Aruba 2920 Switch?

The Cisco Aironet 1140 Series supports IEEE 802.3af standard so it shouldn't be an issue about PoE if it is properly configured Switch side (thus the question: how it is actually configured switch side?).
