If you are there to watch the machine, having task manger rinning in the background and seeing if you can see anything when it stutters would be my suggestion.
I assume it's the PC (source) stuttering rather than the stream.
I also assume you have the operating system and music on SSDs.
Windows update is one suspect for stuttering PCs.

this seems to be happening frequently the past few days now. I am streaming my station online and its not great as listeners are staring to complain now today luckily i have been here when it has happened more than twice in the past 2 hrs. the software is on a desktop that only has the play it live program and that is all and also any music i have loaded onto the system for the playout to run when no live djs are playing. I Know its not the tracks as they are tested and working fine on other devices.
