Mea culpa, bad reading and c&p problem. Yes, Solaris allows to set FD_SETSIZE directly during compilation, so, "Linux" specific ISC_SOCKET_FDSETSIZE isn't the correct value to set. >From the source code, -P2 improved UDP file descriptors handling, but the amount of file descriptors for select() arrays is still high. So setting FD_SETSIZE for some higher values (depending on your load) in CFLAGS is still valid for -P2 releases. Best regards, Milan
