But, I get issue about "Too many open files". To test it, simply I create many dummy files and open it. Here the steps Download source code to generate & load files: * https://gist.github.com/juniorh/3b2fb0a80cddb8e407b3 * https://gist.github.com/juniorh/ef9273911dee551f1048 # create files > mkdir /tmp/1 > python dummyFileGenerator.py -r 1 -n 1000000 -d /tmp/1 # open all files > python dummyFileLoader.py -r 1 -n 1000000 -d /tmp/1 Then, after the script open 32766 files, error occures like: ================================= ... ... open file number: 30763 retry openfile 32766 Traceback (most recent call last): File "dummyFileLoader.py", line 69, in <module> File "dummyFileLoader.py", line 54, in openfile IOError: [Errno 24] Too many open files: '/tmp/1/00/00/7f/fd' ================================= It seems FreeBSD only alow each PID to open up to 32K files. Changing kern.maxfiles and kern.maxfilesperproc is also not solved the issue.
