dev-poll interface FD problem on Solaris 10 for non-root users

[mandyw]

When a non-root user starts Lighttpd with the event-handler set to solaris-devpoll, the CPU pegs at 100% and the log file fills up with the message:

...(server.c.1429) fdevent_poll failed: Invalid argument

This is the same problem as that reported and fixed in ticket #372 with the exception that this is for non-root users. There are two code paths for setting max_conns in server.c, the fix for 372 was applied only to the code path for the root user, but it's also relevant for non-root users. The fix is to add the line:

if (rlim.rlim_cur > 10) rlim.rlim_cur -= 10;

Just after the call to setrlimit in the else clause of the if (i_am_root) condition.

Should be fixed in [2082] for #1562.
Testing/feedback is welcome ;-)
