Also, it is very important on solaris to build with FD_SETSIZE (or something like this, the option is in the makefile and the readme and I don't have it at hand). Solaris defaults to 256 file descriptors by default for one process, and above that you cannot establish any connection, which looks like your case. Also, you should enable poll() support, which is faster than select (although solaris emulates select with poll).

You should also check your system's fd limits. I remember there were two params such as rlim_fd_cur and rlim_fd_max. Don't push them too far, some old applications *might* break. But I know people running them at 4096 without problem.
