I got. I also find that the outage event and client bridge death can be
found in hostapd debug logs. That is, when outage event happens all wds-
stations lost connections with wds-ap. Forget to mention I have about 6-10
stations and all connected to one wds-ap. Do you think by any chance this
is a hostapd related issue? If you have found the origin of the issue or
get a solution please send me an email. Thanks a lot.

I tried set wireless bridge with relayd instead of wds and the problem
went away. Connection is stable for more than two days. And my hardware is
QCA9531,I guess yours is AR9344? It's very close of the two chips,right.
As you do not want to go on with this issue, I have to solve this on my
own...that is sad. One more thing ,I found some ancient posts similar to
ours across 10 past years... thanks for you reply anyway.
