Openfire 3.7.1 large traffic spike from OSX users


I’m seeing very large spikes in packets from all users running iChat and Messages across a few versions of OSX to our Openfire server.

I’m just wondering has anyone seen this before or is there something I can do server side to prevent RAM/CPU usage spiking (I’m guessing this is what’s causing the CPU to get chewed).

This does not occur with users using Adium on OSX or any other IM client on any other OS.

E.G. During the same conversation

Adium user on 10.7.5 Packets Received/Sent: 448/1,243

iChat user on 10.7.5 Packets Received/Sent: 4,010,779/4,011,745

No files transferred, or video/voice chats etc, just standard text.

110 users

Openfire 3.7.1

Monitoring Service 1.2.0

Java 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03)

Sun Solaris 10 u7

Apologies if I’ve left something out.


Yep, we’e seen this with iMessage/iChat. We pretty much just tell people not to use iChat and install Adium instead.

I never got to the point of looking at the traffic the user is sending to determine what it is doing.

Cheers for that David.

Appreciate the reply.
