As many of my users are accessing their mail remotely, I've seen
service loads increase and came across this log messages which I
haven't seen before

        imap-login: Error: socketpair() failed: Too many open files: user=<*>, 
...

I gather I have to increase file descriptor limits, which is currently
set to match

        default_client_limit = 1000

What should I set "ulimit -n" relative to client_limit? Or perhaps I've roofed

        service imap-login {
                process_limit = 2
                ...
        }

and should adjust that?
