How are you handling the MESSAGE packets? You should be able to simply do;
if (method == "MESSAGE") {
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
t_relay();
break;
};
It all really depends on your config. We don't handle MESSAGE
explicitly, instead we explicitly handle methods that require special
handling (INVITE, REGISTER, etc) and then all other messages pass
through the bottom of route[0] which looks like:
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
}
t_relay();

That appears to be exactly what's happening.... it
loops because there doesn't
seem to be any part of the code where MESSAGE is handled. It's ignored by the
t_relay, and doesn't have a specific handling block of any kind, so it's just
looped around until it's too big to deal with.
I just don't know what portion of the code is SUPPOSED to handle it, so I'm
not sure where to go about looking for the source of why everything ignores it.

http://lists.iptel.org/mailman/listinfo/serusers There is a check for message size (which is the
same as it's always
been):
if (msg:len >= 2048 ) {
sl_send_reply("513", "Message too big");
break;
};
Why don't you capture the SIP packet with Ethereal an verify if it
is indeed greater that 2048 bytes. I really doubt it. I suspect
your packet is looping several times on the same SER and growing in
size as more headers are added until it eventually reaches this huge
size.
Modifying this has no real effect on the return,
and the MESSAGE being
sent shouldn't in any way have gone beyond that size. That check's
always been there, though, and I know this has worked before... so I'm
wondering what might have changed, if anything... or if there's a
'standard' way of handling SIP MESSAGE methods that I'm completely
missing.
