Hello,
I'm not sure when the latest SRTSP64 version was released, but I believe that is when I started seeing a problem on a Win 8.1 machine running Norton Anti-Virus where the system would basically stop responding (mouse and int's worked but spinning cursor, white background on explorer.exe, not responding attempting to end processes, etc..) and would have to power off the system. It seems to occur more overnight when system sleeps, wakes up and does a large amount of IO for backup, then goes to sleep again (a cycle of a couple or few days you see it, but if you run back to back all day long not as many problems). The system has been running a long time with no problems - this started all of a sudden. Had some others using Norton check it and they can reproduce as well with same symptoms. I wasn't sure if it was the March Win 8.1 updates from MS (that's what I thought at first - but looking at the dump seems to say otherwise). Also now the other person who has had the setup for years running nighly did april windows updates for Win7 and is now seeing the same type of thing. I'm not sure if he also updated some component of norton at the same time or one of the MS updates is causing an issue with norton? Anyway, I have full machine dumps so could a developer or lead for SRTSP64 contact me privately. Thanks.
This is the latest version of SRTSP64 being used (is there a newer one to try?)

There are a bunch of threads similar to below which I don't think are progressing (for one the application that was stalled was simply deleting a file and it was in that state for hours):
