AP has experienced numerous associations, since last reload.
Running AireOS with the CSCvd27365 fix.
IOS, not AP-COS APs.
APs in local mode, not FlexConnect mode (track CSCve81269 for similar symptoms in FlexConnect)
Clients roaming.
Workaround:
Reload AP.
Further Problem Description:
This bug will address AID problems with local mode APs. For fixes to AID problems with FlexConnect local switching, track CSCve81269.
This bug is a regression caused by the commit of an earlier attempted fix of AID problems, CSCuz49804, in 8.0.150.0, 8.3.140.0 and in 8.4.100.0. Since CSCuz49804 was not committed to 8.2, this bug CSCve81314 does not affect any 8.2 release.
