Analyze audio is processing intensive, so maybe it is stressing the computer. But this would be 1 time only, so I don't know. Better ask in the Interact JRiver forums for official support on that.
It simply hammers the CPU, but RAM and Disks should be fine with no issues. But even that can be rectified with lowering the process affinity. I just think it possibly has something to do with that window that's used while analyzing is occurring. It auto scrolls and sadly doesn't allow a per-session scan categorization of completed scans vs not completed to be separated if you have scanned files already and are using the option to scan already scanned files.
Again, the issue seems to be long active times of nearly anything.. If I have large playlists constantly loading into memory (I only do per-song load into memory non decoded, as decoded was even less stable if you have DSP and are scrubbing or doing too much of anything like jumping tracks and such), the program will eventually shut down randomly if I am scrolling throughout the UI and doing other things on the computer. I am running 16GB's of RAM, 4790K voltage and frequency locked to 4.5Ghz, with task manager always running. There are no anomalies visually from the processing load ever really. I think it's just a combination of DSP, WASAPI, loading into memort, scrolling about in the menu's and such, that the program decides to choke up and just turn off suddenly in a split second if I an rebuilding thumbnails or such. Media Network is it's own issue. It will crash(the whole program) in less than 24 hours no matter what, at all. Play music or not, the server will not stay up. I understand if it has to shut down due to dynamic IP issues perhaps, but why would it have to shut down JRiver, that I don't get. (it also shares a "scan" window issue, where in the media server tab you will see all the pings of the network in real-time, and it's just a constantly feeding log that never ends, so it perhaps causes the program to eventually turn itself off, might have something to do with perhaps me having caching of all sorts turned off, like no pagefile being enabled).
I should do more investigating, but I'm just too lazy truth be told. And it's not too much of an issue given how great this program is. But I find myself wanting to stream more and more, so I'll probably try another computer just to see if the issue is with this one.
