[Users] presence: dealing with publish

Hi, I am using openser1.2 If the presence module receives a PUBLISH: - without E-Tag, it gets stored and if needed, a NOTIFY is generated ... works for me. - with an E-tag, for which this openser has not seen the first PUB (the one without E-tag) ... it gets discarded/ignored? How is the e-tag used in processing publishes and then generating notifies? I ask this because in my (peculiar) setup with two openser's sending publish to each other, depending on the order I start the elements (2 phones, 2 opensers), I don't get always a working behavior: - if the opensers are running before the phones start ... no problem ... I guess as they see the PUB without e-tag, it all goes fine - if the boot order is : openser1 ... then phone 1 ... sometime after (enough to miss the first PUB without e-tag) ... openser2 ... then phone2 ... Phone 2 does not receive NOTIFYs of status changes from phone1, eventhough the PUBlish messages do get to openser2 ... but somehow, they get "discarded" ... Regards, Cesc
