CSCvt10138 - 3700 AP run-out of buffers for bpid 2

[shu shen]

Hi everybody

I encountered a problem that the AP automatically dropped and the client could not connect. The AP needs to be restarted to solve the problem, but after one to two days, the same phenomenon occurs. Query the AP logs and found the following errors:
*Aug 5 05:43:31.919: %DPAA-3-ERROR:! MAJOR BM Error Invalid State; run-out of buffers for bpid 2
-Traceback = 1294CC8z 2EC7B34z 2E5E1ECz 2E554C4z 161E7B4z 2E56524z 2E68B38z 2E62EA4z 2E62314z 1543EA8z 153FAA4z 153FAA4z 1543F70z 153230Cz 1532308z 140FAD8z

Check the Cisco website, it seems to be BUG with CSCvt10138. However, no repaired version is provided.
I have upgraded the version of the 5520 controller to the latest version 8.10, and I still have the same problem.
Please help!

 - If the problem is known by Cisco , as you found out, and no-resolving versions are provided then your only source for support is TAC.

Do you use Multicast on the wireless?
