> After I publish a presence status message I publish another

> 
> The case is used as follow:
> When I sign off from the server OpenSIPS as a client user, I send two
> "PUBLISH" messages: one is to publish with status "invisible" and the
> other with "Expires=0" for unpublish purpose. Server OpenSIPS is
> expected to send 2 "NOTIFY" messages out to all my subscribers and it
> works well in most cases. But sometimes OpenSIPS only send one
> "NOTIFY" with "Content-Length=0" out and it causes the behavior wrong
> in my subscribers clients. After investigation I found the "Cseq" in
> this "NOTIFY" is incontinuous with the previous so I guess OpenSIPS
> misses sending another NOTIFY. Does anybody have any idea on this? Or
> could you tell me how to find the help info? I will appreciate your

> My OpenSIPS is 1.4.2-notls (i386/linux), which I get from "NOTIFY"
