Under Sun OS 4.1, there is a way to increase the number of descriptors a program has opened from the soft limit of 64 to the real hard limit of 128. Right now the Xserver uses the soft limit, could somebody let me know where such an allocation is done in the actual MIT X server? If I knew where to look, I could probably do a patch which I would be quite willing to distribute afterwards. And yes I would put appropriate ifdef's so that it would still compile on other platforms :-). Alain Brossard brossard@sasun1.epfl.ch

(Bet you thought everybody'd forgotten! :-) Look in os/4.2bsd/connection.c... void CreateWellKnownSockets() { ... #ifdef hpux lastfdesc = _NFILE - 2; #else lastfdesc = getdtablesize() - 2; #endif /* hpux */ if (lastfdesc > MAXSOCKS) { lastfdesc = MAXSOCKS; if (debug_conns) ErrorF( "GOT TO END OF SOCKETS %d\n", MAXSOCKS); } WellKnownConnections = 0; (The above is roughly correct, but may not be precise, as it is regenerated from a locally-modified version. The essence for these purposes is correct.) Just before the assignment to lastfdesc would probably be a reasonable place to raise the soft limit to the hard limit. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu

For anyone who cares, note that S5R4 has the same kind of hard and soft limits for file descriptors (and other things; it's your old friend "getrlimit()" and "setrlimit()") so you could do the same sort of thing in a server on S5R4.
