Hi Matt, Yes, there is a risk of overflow. >From my understanding, the id is signed, so you will hit overflow at 2G rather than 4G resources. This applies to any/all PHP/ZE resources.
I'm not sure what happens when it overflows; it seems like the query would fail. You could design your application so that it re-runs itself when the query fails (pcntl_exec(), or one of the other execution functions). --Wez.
