FMS2 Total Clients reach and FMS stop works

Question

Hi everybody,
I have developed one application using FMS2 and Flash CS3
that creates a multi-publishing live stream. I am using FMS2 2.0.5
r88 with license template 2500-25.pro.
The application have two parts:
Publisher (can be max 900 distinct users);
Viewer (can be max 100 users);
After some “Publisher” client put its camera
online the application put it in idle mode waiting for some
“Viewer” client connect and ask to watch that stream.
In this moment the Publisher client start to publish the video
“LIVE” to the Viewer client and everything work good.
When the Viewer client disconnect then the Publisher client goes to
idle again and stop to sending the live stream into the FMS,
waiting for another Viewer client again.
So far so good the application works great until now.
The main problem is that one bug appear all days after 15
hours connected (around 15:00 to 16:00 hours) the app stops to send
any video to the Viewer client that only can see the blank video on
the screen.
When this happened I saw the following info in the FMS2 Admin
Panel:
FMS CPU is over 50% and its frequency almost linear in the
graphic, rather the start scenario where the frequency was like a
square-wave well formed and all streams was working good with good
image.
Total Clients count 2500 or more
Active Clients count more than 750 – 1000 clients
connected (max license used is 2500)
Rejected Clients around 10.
If I restart the application in the bug time the streams
start to work again, the FMS CPU goes to square-wave in the graphic
again jumping between 0 to 50% max, but some streams are swapped in
the server memory cause is possible call for a stream and get
another live, like a copy. The solution is to restart the FMS2
Server service and the FMS2 Admin services on the Windows Services
Panel and everything go back into normal condition.
I hope somebody can help me, because I don’t know if
the Total Clients is the problem or what I can do to avoid that
processing problem. In fact is so curious why the FMS CPU grow in
the time also.
Thank you everybody.
Willismar.

Hi...
Recently I asked for my business, buy the new version of
Flash Media Interactive Server 3.0 , because only this version can
handle multiple independent broadcastings. After buying and looking
for updates on the Adobe forum, I found that a similar problem
exists in the new version, but this problem is identified by Adobe
as a problem of Microsoft's Windows Server 2003.
‘The heavy use of Winsock programs may exhaust the
nonpaged pool memory of a Windows Server 2003-based computer.
Then I got one idea. Before install the new version I thought
in test the MSHotFix over the Media Server 2, but it doesn't
worked. As my idea did not work, then I installed the new version
and did its updates too, and after starting the application for the
first time, noticed that the square wave on the performance tab was
well defined at this time like never before.
During 15 days I only had the same problem once because a
peak in another application that runs on the same machine. After
that never had the problem again.
I think that the version 3 is much slower than the version
2, although better manipulate the connections. Anyway I am writing
my application again to try to optimize the performance of the CPU
and prevent the problem go back again some day.
The HotFix can be found here (

if you want to try with the FMS2, but I only got good results on
the FMS3.
If you have any question let me know
