Re: maximum number of open sockets, files, threads, etc..?

that is ancillary memory per socket. The maximum number that can be open on a machine is capped by maximum FDs (an fd is a 16 bit number, right?), not total memory taken by all sockets.

Yeah, but fds are per-process indexes into a per-process table.

ok, so you can set it to whatever you want for the box by echoing into file-max. So the theory limit is 1024x1024 (memory willing?) fds?

#define NR_OPEN (1024*1024) /* Absolute upper limit on fd num */
#define INR_OPEN 1024 /* Initial setting for nfile rlimits */
