AP unable to connect to controller....%SYS-2-MALLOCFAIL

Hi,

AP capwap tunnel is lost to the WLC but on the switch the AP is reachable via ping.

AP is Leighwight 2702i 15.3(3)JK5 and the WLC is 3504 8.10.151.0 (its compatible)

Set up is: WLC > Aruba switch > AP

Note, other AP are connected to same switch but not experience any issues.

WebUI>Monitor>Statistics>AP Join, this is the last error for this is (attached)

#debug capwap cli err

The only solution is to reload the AP because to rediscover the capwap tunnel and service the client. Typically its connecting 40-50 iphone users both AP in the break out area but other AP are working with no issues but this happens once a month. As highlighted its memory issue but i can't find any bugs that are open or fixed on the versions but the closest are terminated.

What can I do? Please help.
