Heavy Network Traffic (->Network message pending)

[Kn1ghtR1d3r 10]

Hello,

my mission was running fine. But now after making a big update for the mission the server FPS are dropping very fast.

I tried to find out what is causing the FPS drop and first of all I noticed a lot more network traffic.

Network traffic was around 6000-9000 kbs with a full server before the update and now it is between 20000-30000 kbs with only half of the players. My assumption is that the network traffic is causing the FPS drops.

The problem is that I can't figure out what is causing all the network traffic. I checked everything and I am pretty sure it's no functions beeing called inside my scripts.

When I have a look at the server log files there are a lot of messages like these:

Server: Network message 2c04130 is pending

NetServer::SendMsg: cannot find channel #830492367, users.card=46
NetServer: users.get failed when sending to 830492367
Message not sent - error 0, message ID = ffffffff, to 830492367 (Playername)

In my client side logs I found these messages:

Observer C Golf 1-3:1 (Playername) REMOTE (civ_13) in cargo of C Golf 1-3:1 (Playername) REMOTE (civ_13); message was repeated in last 60 sec: 14896
Observer C Hotel 1-3:1 (Playername) REMOTE (civ_24) in cargo of C Hotel 1-3:1 (Playername) REMOTE (civ_24); message was repeated in last 60 sec: 34517

Now I assume that those "observer messages" are causing all the traffic, but I don't know what I changed to cause those messages.

Can anyone please give me a hint how to resolve this issue? Or give me some tips on how to find out what exactly is causing the network traffic.

Thanks in advance!

If

"message was repeated in last 60 sec: 34517" == 34517 messages in 60 seconds

Then you have a process that is death looping. You are spawning a message, that is spawning a message, that is spawning a message, etc. Infinite recursion.

Thanks for your help Jacmac!

But how could a death looping process cause all that network traffic? And why is this causing all the "observer messages"?

I need some hints what I have to look for. Is there a way to log what is causing the traffic?

I couldn't tell you what is causing it from what you have shown so far. When you say you made a "big update", how big exactly? Can you show a before and after or is it way too many changes?

Make yourself an overview of all network calls (pV, setVar public, etc) with their frequency and data amount.

I finally figured out what the problem was. It was a trigger on the map.

I called a function in the activation field of this trigger that spawned some animals. And for some reason this trigger caused between 500-1000 kbps traffic per player!

Normally it's only betwenn 10-50 kbps (when standing still).

But thank you all for your help! If you want to try out the mission search for "Blackwing Gaming". It's a life mission.
