Description Christian Nitschkowski 2003-08-31 10:46:37 UTC
Version:           0.7.1 (using KDE KDE 3.1.3)
Installed from:    SuSE RPMs
Compiler:          Gcc 3.3 
OS:          Linux

Yesterday I got the following message from my jabber-server:

I'll try to translate it, but I'll keep it attached for german readers - the original will certainly be better than my translation.

The newest release of kopete seems to cause a problem.
The session-managers of amessage go down more often these days.
The problem seems to be caused by a (each time different) user who uses kopete as his jabber-client.
These kopete-users send without a break identical transport-rename-commands to the server. This causes high loads on the session-manager, so that it isn't able to answer incoming messages in a reasonable time anymore.
If you use kopete: Please switch to a different jabber-client until the problem was found and fixed.

Comment 1 J 2003-08-31 12:37:26 UTC
I received the same message. I am also using 0.7.1. I installed Kopete from the Source with a 
Mandrake 9.1. 
Comment 2 Till Gerken 2003-09-01 11:55:21 UTC
This is strange, I never came across it. Do you actually have transports on your contact 
list? If possible, can you enable debugging at the configure stage and see if the packets 
show up on the debug console? A small log excerpt would probably help a lot. Does it 
happen at login stage immediately or is there a trigger? 
Comment 3 Matthias Wimmer 2003-09-01 12:11:54 UTC
Every user on one of the amessage servers gets the warning about please not
using Kopete at the moment. I had to "broadcast" this message as there is no
feature in the server to send messages to only users of a special client or
client version. Actually the server does not even know which client a user is using.
Not every user using Kopete is causing these problems, but there are several
users, that are causing problems and all of them are using Kopete. (I know this
by asking them which client they use and because they are using the Resource
"Kopete".)
If the problem happens it is always that Kopete renames _one_ of the transports
on the roster all the time. E.g. one user renamed the AIM transport between
"Netübergang: AIM" and "AIM" all the time in both directions by sending <iq>
sets with a <query xmlns="jabber:iq:roster"/> element in it.
When I notice that this happens I think I always noticed that the corresponding
transport has been down. I am not sure which event implies the other. Is kopete
trying to log in again to a transport, that is offline?
Comment 4 Till Gerken 2003-09-01 12:23:19 UTC
Kopete does not really support transports yet, so it won't do anything transport specific. 
The only thing Kopete can knowingly do is register with a transport. For everything else, it 
treats them like normal contacts. It could be that users using transports nevertheless and 
trying to rename the transport causes Kopete to get stuck in a loop. Since the rename 
packet is guaranteed to only be sent out once, I don't understand yet why it would get 
sent out repeatedly. 
Comment 5 Till Gerken 2003-09-01 18:06:41 UTC
I cannot reproduce this. I registered an account tigloo@amessage.de, registered with the 
ICQ gateway, disconnected and reconnected. Nothing happened. I renamed the transport, 
nothing happened, not even after reconnecting. 
 
I need to get exact steps to reliably reproduce the behavior - maybe someone can create 
an account for me where it happens and let me access it? 
 
At least a full debug log is required, otherwise I can't work on this. Since by design there 
is no way that the Jabber plugin will get into an endless loop sending out the same 
packets over and over, I currently have to suspect that another part of Kopete is 
responsible or that there is an error on the server side. 
Comment 6 Till Gerken 2003-09-01 18:30:34 UTC
Adding kopete-devel@kde.org and asking for help: could a few people using the Jabber 
plugin please test this with one of the amessage servers? 
Comment 7 Till Gerken 2003-09-04 16:38:03 UTC
Since there have been no further reports about this bug, I'm lowering the 
priority and severity again. AFAIK this is the only bug preventing a 0.7.2 
release and we should try to get 0.7.2 out of the door, especially concerning 
the fact that it might make it on the next SuSE distro with an updated MSN 
protocol. 
 
In case this bug turns out to be a fault in Kopete's protocol implementation, 
I'd much rather release 0.7.3 as soon as there has been more evidence and a 
potential fix. 
Comment 8 Till Gerken 2003-09-22 19:40:59 UTC
There have been no further reports or follow-ups, even though the bug is now 
three weeks old. I am taking this one very seriously, but I'll have to close it 
if there won't be any incidents after the next few weeks. 
Comment 9 Christian Nitschkowski 2003-09-22 21:48:53 UTC
I even don't get any message from my jabber-server a-message.de regarding this 
problem. 
Maybe it wasn't really kopete's fault? 
 
Comment 10 Matt Rogers 2003-11-05 07:21:21 UTC
No further reports or follow-ups, so I'll close it.

Till: If you think this one should stay open, feel free to reopen. :)
Comment 11 Till Gerken 2003-11-05 08:33:56 UTC
It did occur once again, apparently not in the frequency as before but still it did happen. Matthias sent me a packet dump, it's almost impossible to diagnose it without the corresponding debug log though. I'd like to keep this open until the next major release after 0.8, if it went away by then, it was temporary. Otherwise I'm hoping to get ahold of more information.
Comment 12 Martijn Klingens 2004-01-18 11:45:13 UTC
If this is to stay open for such a long time it's not a 0.7, nor a 0.8 version :)

Does this bug still happen? With major changes in the Jabber code coming up and no follow-ups to this, I am inclined to close it after I merged the new Jabber library.

Comment 16 Till Gerken 2004-03-10 00:27:28 UTC
The new Jabber code has been merged to HEAD this afternoon, with Matthias having given his approval I'll close the bug for now. Let's hope it won't come back. :)
