Hi,
We have a stress testing tool for our hardware RAID controller that
spawns lots of threads, then writes lots of files and reads them back
to verify the data.
Under some configurations, which cause heavy VM paging, there are
comparison failures. Under other configs that don't stress the VM so
much, it works correctly.
My coworkers think this could be a bug in Leopard's VM implementation.
If that's the case, Apple certainly needs to know about it, but the
bug is difficult to reproduce - one has to leave the tool running for
hours, for example.
Whether it's Apple's bug or mine, I certainly want to find the cause.
I'm not sure how to proceed. Can anyone give me some debugging tips?
Thanks,
Mike
