openLocalStateFrom seems to have max limit on file count

I made a test that just makes a bunch of counters and breaks acid-state. with a resource busy .

since the counters are just being opened in sequentially numbered directories it doesn't seem like there should be a problem.

You're not closing any of the databases so maybe you're running out of file descriptors. Try changing the ulimit and run it again.

I have ulimit set to 10k soft and 100k hard. It is breaking at 500 open timers.

Here is the output from the program after I added in a milisecond delay between state opens.

08:59:52-scott~/programs/reference/broken-acid-state-test (master)$ ./dist/build/acidStress/acidStress
"stressing system"
acidStress: <file descriptor: 1026>: hClose: invalid argument (Invalid argument)

Here are my ulimits settings...
