Hi, I am having trouble with increasing the file descriptor size for my application - it opens several files for each client session (and needs to keep them open as long as the session is active, which can be upto 3 hours long). What I see from the application is "open failed in FileStreamReader::setupFile: Too many open files". I have bumped up /proc/sys/fs/file-max to 16K, but I am failing at 2638 (cat /proc/sys/fs/file-max returns "2638 97 16384") when the number of files my app opened reached 1023. There is a comment in /usr/include/linux/posix_types.h regarding __FD_SETSIZE being set to 1024. How can I increase this value? Thanks, Ram Madduluri
