[jitsi-dev] Jit.si federation problem


#1

It seems to me that there is a problem with federation and the jit.si
server, i was unable to contact anyone having an account on that
server from another server; i was able to contact them when using an
account@jit.si so it seems to me that there is an problem with
federation (it is not the server i am on, i was able to contact users
on other xmpp servers)

Could you pkease try again? We were hitting a max_open_files cap beacuse of
a high number of connections.

I need to correct myself:
now all my contacts from jit.si are shown as away, which is not the
right behaviour in my oppinion

Another reminder that this has not been resolved yet, the opposite: it
got worse.

while i was able to contact accounts@jit.si some days ago using a
third server now even that is impossible.

i notice that another server (test.jit.si) has been added which even
fails to let me log in?

It is still not resolved, additionaly i can not login with my
account@jit.si anymore. maybee you should switch to another (higher
performance) jabber server (which is not java based) and/or close down

Good catch. Jitsi automatically tries all records but I guess other
servers don't necessarily do this. I've just lowered swing's priority.
Let me know how this works.

It is still not resolved,

OK, we'd have to look one of these days. Federation is working for a
number of destinations and I am not sure what fails when it doesn't.
If any of the people running federated servers can shed more light on
this, it would be very helpful!

additionaly i can not login with my
account@jit.si anymore.

Strange. Everything seems to be running smoothly right now. What
happens when you try to login?

maybee you should switch to another (higher
performance) jabber server

We probably will. Tigase is one candidate. That said, the performance
cap we were hitting was a linux one and not related to Openfire. We've
changed the configuration so hopefully this specific issue will not
appear again.

(which is not java based)

Interesting. Why would we want to avoid Java?

Generally speaking, I don't really have a language preference,
especially when it comes to our XMPP server, although Java does have a
slight edge: we are a Java project. This is probably the one language
that's in the skill set of all project developers. If we ever had to
look into server code it would seem to me that Java would be a
convenient coincidence.

and/or close down
registrations&

Hopefully we won't need to do this.

implement federated registrations instead

What's a federated registration?

ok, there are no more errors when i try to log into account@jit.si

Let me know how this works.

not really, adding the contact still does not work, but that might be
because of the dns caching, so i will just wait about quater an hour
and try again.

It works again now, it told me that my password would be wrong,
changed nothing, works again.

Interesting. Why would we want to avoid Java?

Because while being portable Java is always slower then a native
program and its memory consumption is sometimes horrible. Choosing a
native program oven a Java-based is just logical in limited-hardware
situations like the one you are in.

Generally speaking, I don't really have a language preference,
especially when it comes to our XMPP server, although Java does
have a slight edge: we are a Java project. This is probably the one
language that's in the skill set of all project developers. If we

would be a convenient coincidence.

that needs to be taken into account of course but: how high is the
probability of that happenings

Strange. Everything seems to be running smoothly right now. What
happens when you try to login?

It works again now, it told me that my password would be wrong,
changed nothing, works again.

Interesting. Why would we want to avoid Java?

Because while being portable Java is always slower then a native
program

Well, this is simply not true. It might have been the case 10 years ago but it no longer is today. I encourage you to lookup C++/Java comparison performance tests.

and its memory consumption is sometimes horrible.

Just as it is sometimes horrible with any other language.

Tigase on the other hand can run within 10 MB of RAM. Openfire is not particularly greedy either.

All in all this sounds to me a bit like anti-java religiousness and this is certainly not the right mailing list for this.

Choosing a
native program oven a Java-based is just logical in limited-hardware
situations like the one you are in.

Er ... why are we in a limited hardware situation? We are not running our XMPP server on a Raspberry Pi.

Generally speaking, I don't really have a language preference,
especially when it comes to our XMPP server, although Java does
have a slight edge: we are a Java project. This is probably the one
language that's in the skill set of all project developers. If we
ever had to look into server code it would seem to me that Java
would be a convenient coincidence.

that needs to be taken into account of course but: how high is the
probability of that happenings

It already has. We often run Jitsi Videobridge as a plugin for Openfire.

Cheers,
Emil
