We search without sucess on the Internet for the meaning of this error logs.

 

Can someone explain the problem ? ( if it is a problem ).

 

Regards.

Re: system log kernel error

hi

 

are there any users on the APs when these messages are occurring ?

do the messages stop when there are no users ?

if you reboot one AP that has the logs, do they come back within (say) 1 day ?

what are the client types ? (macs, windows, mixed, what chipset?)

 

it's possible there is some user impact, it may also be unnoticed by the users - need to get some more information.

Re: system log kernel error

 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

Re: system log kernel error

hi, sorry for the delay. there are two issues evident:

 

a) log flooding of this message where "seq 0" is seen

Jan 22 14:25:20  KERNEL(DYDDD1AP04@172.29.123.211): [12112.805654] === Reducing pace for error prints ==== 
Jan 22 14:25:20  KERNEL(DYDDD1AP04@172.29.123.211): [12112.805654] Start seq_num 0 End seq_num 0 tid 16 failed seq 0 - error occured 1800 times

b) a self initiated crash that comes when this message is seen, where "seq -1" is seen

Jan 22 14:30:31  KERNEL(DYDDD2AP03@172.29.123.214): [344635.831906] Start seq_num 0 End seq_num 0 tid 16 real failed seq -1 win_mask 0 vdev (80:8d:b7:e4:20:42) peer d863e000 (e4:b3:18:3c:18:60)

Jan 22 14:30:32  KERNEL(DYDDD2AP03@172.29.123.214): [344635.833062] [wifi1]: XXX TARGET ASSERTED XXX

For b), it's resolved in bug id 191696 which is fixed in 8.x software but not yet 6.5.x , it's pending patch - check back in a few weeks

 

For a), it's not fixed - R&D needs more info (bug 180612), if you're able and willing to do some further data collection, send me a private message and we can discuss it via email rather than the forum

 

regards
