Pending AIO operation, recycle later...
Issue: Litespeed became non-responsive suddenly, websites couldn't be accessed. After restart, litespeed worked again.
The issue occurred three times.
Log: I checked litespeed logs, found lots of "Pending AIO operation, recycle later..." message when litespeed was not responsive.
The server has 48GB ram, AIO is enabled and AIO block size is 8M.
Was AIO cause the issue? How to solve the issue please?
