<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I believe this should be (!peer->maxms). 0 seems to mean Unmonitored. Negative is undefined as far as I can tell, but all checks are done like !peer->maxms.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Don't you mean if (peer->maxms)?
If peer->maxms is 0, then the peer is unmonitored and we shouldn't poke at it. If peer->maxms is non-zero, then we should poke it.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">with a big amount of sip peers registered doing a sip reload causes a packet flood of sip OPTIONS messages cause they are immediately sent out when the peer is loaded back from the astdb.
This fix prevents this packet storm and just schedule a poke in a random value between 1 ms and peers qualifyfreq or the global qualifyfreq.
Another very small fix is to schedule a poke on peers with qualify disabled. This doesnt cost much but its just unnecessary to do this.
maybe it would be even better to dont call the poke function from source_db on a reload cause poking all peers is done after this again.</pre>
