Zysh Daemeon Busy Error / not accessible via Web GUI

nuke

I get frequent error message "Zysh Daemon Busy" during access on USG110 via Web GUI.

Sometimes Web GUI gets irresponsive, then displaying "Wrong CLI command, device timeout or device logout".

Rebooted USG couple of times without change of behavior, current firmware installed. V4.35 AAPH.3

Symptoms started after one of those firmware updates last summer, show up inconsistently, but now more frequent and consistently blocking work.

Research in forums show similar problems showing up in older firmware versions, then resolved.

Some posts suggest browser issue. I tried latest Safari and Chrome on a couple of Mac Systems. Don't have access to any Windows box to try different browser.

Any ideas?

Had Zyxel remote on my firewall last fall, but miraculously error did not show up during whole week of remote watchdog. ;-( --> wasn't helpful.
