Has anyone experienced issues using ASYNCHRONOUS IO with the current IVF classic?

 

After about 950 asynchronous (read...wait) using ID=n the wait hangs. I do not have a simple reproducer handy. Just want to know if others are having issues or success.

 

The failure point is quite consistent independent of using one thread or multiple threads (each with own ID's).

Jim,

 

I searched the bug database, nothing open at this time.  You are on Windows, just to confirm (you said "IVF classic" which I assume is Windows).  Because I did close an issue on linux where async IO hung when build with -static but not when built with -static-intel (seems like the static version of glibc was at fault, not the compiler).  On Windows you would be building dynamic, not static.
