AP: Not receive heartbeat reply

[yzaari6166]

Hi,

We are experiencing APs crash each day and it is random below is what I am getting form the crash log:

spamApTask4: Mar 13 23:46:47.061: %CAPWAP-3-ECHO_ERR: capwap_ac_sm.c:7546 Did not receive heartbeat reply; AP: a0:e0:af:99:ef:a0

AP Model: AIR-AP3802I-B-K9

WLC Module: AIR-CT5508-K9

Software version: 8.2.141.0

Please advise

Thank you

It sounds like it is having trouble communicating with the WLC.  Is the WLC nearby, or on the end of a WAN link?

I see 8.2.151.0 has also come out.  You could try upgrading to that.

The release notes do mention this resolved bug:
