Error from libf4f.dll: failed to swap file

Question

We did a live stream last night using bitrates of 282 and 482, and the video was terrible, constant buffering on client players. Now looking back at the recorded video it looks corrupted audio and video out of place, video is pixelated and stuck. The encoder has over 2mb of upstream bandwidth for encoding so it's not the problem. The problem is FMS interactive server. We are using version 4.5.0, I've setup another instance usinf FMS 4.5.3 will this resolve the issue? According to the FMS 4.5.3 release notes this error is a known problem. How can we stream video like this?
Our server logs in event viewer show a ton of FMS(Core) error msgs about
"error from libf4f.dll: failed to swap file C:\FMS\applications\livepkgr\streams\_definst_\*****"
How can we resolve this issue? The FMS is useless in this state.

Answer 1

Client is streaming from a remote location (a hotel with PLENTY of bandwidth, 50MBs I think) back to the FMS on our VM server.  This is the only stream on the going thru the FMS box at that time.  The video output from the TriCaster goes to a canopas box through BNC. Then in the back there's a firewire that plugs into the "streaming" laptop. That laptop is streaming out with Flash Encoder and hardwired into a router.  That router is plugged into the internet provided at the hotel.  The stream averages anywhere from 200-250 viewers/connections.  We are delivering stream to viewers via RTMP/Flowplayer front-end for desktop users and using the HTTP streaming link for mobile users.  Client is publishing stream at 350 kpbs via Adobe Live Media Encoder.
Does that help?
