[Solved] PC 'Stuttering' after UMS running for a while

[Nadahar]

As you said, most things looks good in the log file. I do however see something I find somewhat unusual:

Code: Select all

TRACE 2020-04-27 02:29:04.202 [UPNP-AliveMessageSender] net.pms.network.UPNPHelper Setting SSDP network interface: name:eth2 (Broadcom NetLink (TM) Gigabit Ethernet)

There are quite a lot of these, and I have read many such logs in my time. I can't remember having seen this. It also looks to me like it receives an unusual amount of UPnP "NOTIFY" messages. These are part of the UPnP discovery protocol (SSDP), and one theory could be that UPnP/SSDP interface is constantly being reset, resulting in UMS broadcasting its presence and receiving replies much too often.

That said, I don't have any good explanation of why this would happen. It must be said that I haven't run UMS since 6.x, so there might have been some new bugs introduced since then. I am also doubtful to whether such a bug and the resulting traffic would be enough to cause the behavior you describe. I would think that it would take much more than that, but it's hard to know exactly what such a network interface initialization potentially might include on the OS level. If a socket is reserved each time, it's possible that significant OS resources would be used for this, but I still find it somewhat unlikely.

Except for this, I really don't have any good idea of what might be causing this. I would try a much older version and see if the problem is the same, preferably 6.x or 7.x. With these versions you also need to have Java installed, which could solve some potential issues between Windows Defender (or other such "scanners") and Java.

Okay, so I'm glad it's not just me! It seems like something has changed in the last few weeks then... and perhaps it was just coincidence that it happened around the time I switched to Windows 10.

It would be useful to know which version you are using BlackHamster, and if anything else has change about your system in the past few weeks...

I'm going to try an older version and see if that stops the problem, but there is clearly something amiss.

It sounds like it's a bigger issue then, either something changed in Windows 10 or something changed in UMS. Trying an older version of UMS is probably the easiest route

I've got back to 9.2 and so far, so good. I'm going to leave it on for a while and see how it goes. It would be interesting to see if 9.2 solves your problem too.

[speckledegg]

No, it didn't solve mine either although it is significantly improved. I've not had the severe stuttering on the mouse etc, but the audio is still fecked.

I think you should try much older versions, before Java was embedded with UMS - but that would require you to have Java 8 installed.
