<!-- Maximum number of file descriptors. Note that the number of

s2s itself can use some on its own. If the supply of file
descriptors is exhausted, new incoming connections will be
denied.
These connections are mainly consumed when we make a
connection to an external jabber server, or an external jabber
server connects to us. If you don't have a lot of users then
there's probably no need for s2s to establish connections to
external jabber servers and the default value here is probably
fine. On the other hand, if you have lots of users with lots
of remote buddies in their buddylist then s2s will need to have
lots of open connections with other jabber servers and you may
need to increase this value.
Note that this value only affects how many file descriptors
jabberd is able to handle internally. You may also need to
tell your operating system to allow jabberd to use more file
descriptors. On Linux this can be done using ulimit -n or by
changing the value of /proc/sys/fd/file-max.

While a connection is being established and dialback is in

setting up a route authenticated through dialback:
1. Connection establishment to exchange of stream headers
2. Initiating dialback (incoming connections)
3. Completing dialback (incoming and outgoing)

recently, they will be tried too before finally giving up.
