Hi! In a class derived from thread I open a socket-Connection to a remote Server. Here I start about 500 Thread's on a solaris-System. Sofar there is no problem, when the filedescriptorlimit is set high enough with ulimit -n.
My Problem is, when a function in the class tries to open a regular file in the filesystem. Because of some limitations of the FILE-Structure ( in C ) it's not possible to open more files than 255. I think, that this is the problem here in python, when open() delivers "too many open files". In my C-Daemon I duplicated the socket-descriptors with fcntl to start after a offset with e.g. fcntl( socket, F_DUP, 100 ). And after this I use the new descriptor and close the old one. So there are everytime some descriptors below 255 ready for opening regular files. I tried the same thing in python. socket.fileno() delivers the descriptor of the opened socket. The fcntl-Call in the module fcntl does also succeed. But after this I need a socket-Object for working on with the new filedescriptor. Constructing a new socket-Object with socket.fromfd() does not work, because this takes a new descriptor at the same low offset. Is there any possibility to get a socket-Object which uses the allready obtained filedescriptor from fcntl()?
