[SR-Users] Daily crash of kamailio 4.0.5

[Tristan Mahé]

Hi guys,

I'm having some crashs on a simple REGISTRAR, in st_delete_ucontact.

It happens daily, mostly when proxy is loaded. Saw that someone got the
same problem via this pastebin: http://pastebin.com/GsMtav7A.

Does someone got an idea of why it's failing or a workaround or a fix to
share ?

Here is the backtrace for us:

And here is the simple part of config that could call this method:

route[REGISTRAR] {
	if (is_method("REGISTER")) {		
		if (!save("location","0x04")) {
			sl_reply_error();
		} else {
			# DOSOMESTUFF like replicate to a backup proxy
		}
		exit;
	}
}

If you need more info, don't hesitate to ask !!
