Hi,
soory for delay :
are there any users on the APs when these messages are occurring ?
yes there's users on the APs ( 5 to 14 on 2.4Ghz ssid )
do the messages stop when there are no users ?
We will check on night but most of the AP that make the log are on place where there is WiFi connected printers.
if you reboot one AP that has the logs, do they come back within (say) 1 day ?
We try to reboot 2 AP that have the logs , they comme back in less than 10 minutes (6 users ).
what are the client types ? (macs, windows, mixed, what chipset?)
Windows PC , printers , and one or two Windows CE barcode readers (Zebra) .
don't know the chipset.
no users impact for now.
controler are 7210 on 6.5.4.10. most of the log 90-95% comme from AP-315. and most of log from 6 AP-315 (we have 20+ AP-315 )
before that with 6.5.4.8 we also have lot of this logs with AP-314 , now with 6.5.4.10 we have 2 log per day ( from 2 AP on 400+ AP314).
Thank for help.
Regards
