Unifi APs lbd exit code 256 repeatedly

Original thread on the unifi forums

lbd exited with code 256 and restarted by inittab, 141,020 times one one AP in 48 hours

This process has crashed more than a few times lately…

Model UAP-AC-IW, firmware Version

The common response from @UI-Glenn was “disable band steering” - which I had done. Any chance of an actual fix soon?

I logged a support case for this, which led to me upgrading the firmware on the Unifi controller (self hosted, on a Ubuntu 20.04.3 VM)

From: Version: 6.1.71 (Build: atag_6.1.71_15061)

To: 6.4.54-16067-1 (Build: atag_6.4.54_16067)

I think that reprovisioned the APs and redeployed the config. Things came good, so far.. I haven’t had it come back yet. and it’s been a month.

Band steering is currently set to “Prefer 5G”.

It sure seems to have helped - these were the syslog event counts during the issue.
