Occasional wireless traffic hang
I am seeing occasional hangs on my WAP network. Ssh to the WAP normally shows 95% idle and 0% isrq for top:

I am happy to report that firmware 3.9.1.0 has been released, and I think it fixes the problem reported in this thread. The release notes document is dated August 13, 2019, mention these two fixes:
1. Addressed intermittent, rarely encountered access point hang issues.
2. Fixed various stability and connectivity issues.I think this closes the issue. I will keep my monitoring in place for another year to verify the fix. Thanks to all who helped.
OK, I will grab the logs once it happens again, though I have sent 50% sirq logs to you before and you said it looked fine.
Last time I got the 50% sirq at exactly 48 hours of uptime. I have passed 48 hours since the recent reboot and the sirq% is still zero. I will report back and grab the logs as soon as my logging informs me that sirq has increased.
