[hybrid] setting connect limit

[x y]

Hi,

we've set up Ircd-Hybrid for a local chat. I't fine, but we're having
overload issues by means of connecting
we typically have a high rate of newcomers in a narrow interval (show
start) and much milder in any other cases, that means few peaks a day
(2-3)
we have spoofed the clients' host
the problem is it refuses many connection, in fact locking out our
office as well :)
how can we raise the limit of new connections? didn't find any .conf
variables for that
would exceed_limit on the 'users' class solve this?
