Render Farm Computer issue with Backburner

[scubasteve02]

One of my Render Farm computer is rendering extremely slow and it seems every frame is getting slower and slower. It started at near 3 minutes a frame is at near 10 minutes a frame now. Another Render Farm computer that is the same build with all the same specs is rendering under 2 minutes a frame. I have restarted the server and it has been happening on multiple projects the past week or so.

 

Any Clues!

Is it getting hot and lowering its clock speed? That would be the simplest explanation.

I have a similar problem. I find all my machines slow down after a number of hours and I have to restart the server on each machine. They are running at a constant temp.

 

I have not been able to find an answer so far

Make sure any software that does auto update, has updates disabled, including windows, adobe, antivirus etc.

It not only slows down access to your disk, it also puts extra overhead on your network

 

Also make sure you're not running a full system or antivirus scan in the background on your slaves

Something i have found on networked desktop machines running backburner is that occasionally it will really mess up and it will be running about 20 processes named backburner taking up gigabytes of ram. these disappear when server is closed. its almost as if it isnt flushing the previous frame from memory. This usually only happened after about 5-7 hours of solid rendering.
