I'd assume it would take a lot of luck to spot such a case by manual testing, even though this seems to reproduce itself rather reliably each morning... But what I could try, of course, is to code a shell script that could repeatedly try that command and see if CellID is returned or not. I could do that, no problem. Next thing I'll do, however, is to install SFOS update 11. Who knows if that might even fix this (assuming it is due to a bug which has been fixed in the platform)...
