Hi all. Running FreeBSD 9.1-Release, I am seeing some absurd hangs (10 minutes or more to open a file) with SIGINFO informing me that the process is stuck on zio->io_cv. Does anyone have any suggestions for what I want to look at to tune this? This is on a newly bought laptop with large amounts of RAM and almost nothing else running. Please CC me as I am not subscribed. -- Eitan Adler
