Please show us a small, self-contained, compilable example of the problem. I have never heard of file descriptor leakage in Qt. > "lsof | grep resrv" gave me a bunch of open fd's:[...] > resrv 12701 root 13r FIFO 0,8 0t0 319902 pipe > resrv 12701 root 14w FIFO 0,8 0t0 319902 pipe Those are pipes. They aren't related to QNAM, since QNAM doesn't use pipes. It could be because of the threads. Each thread that you start consumes 2 file descriptors in the form of pipes (until Qt 5.1 or until a recent enough glib2 in your system, then it's only one). But you said that the number of threads running was only 3, so that doesn't explain. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
