I think i'm seeing a pattern which causes the overflows and there's nothing *I*
can do about these things. This is just 3 clients from 2 different servers but
i suspect the rest will be showing the same stuff. The rest of the data is just
plain small compared to these on those snapshots.

Ah, if you are seeing it mostly on the saxton servers, then that could be a
clue. There's could be some big array or object or something in the saxton
entities being networked inefficiently.
The netspike file should make it obvious where the bandwidth is going. But if
you need some help analyzing it, email it to me directly.

When you update, put in the notes the cvars or whatever you can setup for those
option. Since I only see it on a couple of servers (saxton servers mostly, but
hey I can understand) its actually a nice feedback to know that clients are
having issues and it could be related too a plugin too.

The netspike file has long existed in the Source engine as a way to track which entities
were causing large spikes of network traffic. There's a convar you can use to configure
a threshold when it will get dumped. (I think by default it's off.) Recently there was
a change where, if a client was dropped to the infamous "snapshot overflow"
error, it would re-run the network packing code for that client, forcing the netspike
file to be dumped, to help figure out what entities are the cause of the problem. That
could definitely cause CPU spikes. I didn't realize we had shipped with that debugging
mode on. We'll make it configurable by convar for the next release.
In the meantime, each time it dumps a network trace, it means you dropped a
client. It needed to send them a full snapshot of the game state, but the
snapshot was too big, so it had to drop the client. You might want to see
which entities are responsible for so much traffic, because you are dropping
players.
If there's something particular to your server, this trace will help you tune
it. If you find a problem you think is global to the game, please report it
here.
Your humble servant,
Fletch

i only have it on my registered servers with quickplay.
on my not registered servers there´s no netspike.txt.

yes it looks like debuggin info of some sort. My two servers have
those files to and both are 2.0Gb each....

Interesting.
This file has indeed appeared on some servers on a host which I manage.
In one case, the file is now 1.3GB in size.
I suspect Valve has noticed the same thing I noticed.
When the Pyromania update came out, I noticed that my host was using
much more bandwidth than usual. There seemed to be a spike happening,
intermittently, for limited periods of time. I observed a 30% traffic
in/out increase for 30-60 seconds at a time.
All clients on all servers on that particular host, and all servers
on that host, would suddenly start sending much more data, for no
apparent reason.
I only have a 10base-T uplink on this host, so I am limited to 10Mbps.
All four of the servers were full that day. However, due to the
traffic spikes, we had to shut one of them down to prevent exceeding
the circuit limitation. This is how the issue first came to my
attention.
I did a tcpdump of the traffic but whatever the issue was, it was
embedded in the game traffic itself and was being represented by all
clients on all four servers at the exact same time.
If I was to guess, something like an authentication request or
item-server related activity was suddenly causing all clients and the
server to suddenly transmit much more data. Whatever it was, it would
have been something that affected all clients across those four
servers on the same host.
Valve would have noticed huge spikes like this since ALL of their
servers and clients would suddenly start transmitting 20-30% more
traffic.
I am guessing they are trying to debug the problem by collecting
evidence.
That's just a guess though.

Why is this showing up now, and how can this logging be disabled?
