Built up an Unraid server to replace a WHS system media server that is getting a bit long in the tooth. Setup generally went fine except I seem to have been at the cusp between SW versions. I would look up how to do something in the docs but that info did not match what was on my screen.

Finally got it operating to serve video and video primarily to Dune player. It seemed to work fine for about 3 months with the only "freeze" happening when I first started to watch when all of the drives are spun down and have an understandable spin-up delay.

In the last 3 weeks however as we are watching video, it will simply freeze for 15-30 seconds around about 5-10 minutes apart. Needless the WAF has dropped and I put the current watch list onto a USB drive connected to the Dune.

Here is what I think I know...

The array was created from scratch and the files copied from the WHS server. My guess is thae is not a lot of fragmentation which would require a drive spin-up after the initial load.

The network is 10G up to the Dune where it drops to 2.5G then 1G into the player.

If I watch media on my desktop using VLC freeze is the same (probably not the Dune).

If I watch the dashboard the network traffic drops to zero-ish during freeze nothing unusual on the array.

I ran a parity check no change.

I am thinking of adding a single drive as a non-array source (USB or SATA) to rule out most of the hardware.

I hopefully attached a diagnostic dump.

I don't know what software I am running because I have not found a "About" screen. I am sure it is there I just haven't found it (I did find Linux 6.12.54-Unraid x86_64).

Any suggestions or pointers appreciated!!

I assume the issue occurred during these timecodes?

If yes, this looks like a client problem. Is this the client's IP? remote=192.168.0.235

This log means the client requests a video, samba starts streaming it using sendfile(), client disconnects before the transfer finishes, samba attempts to send another chunk, kernel returns (Broken pipe), samba logs it and terminates that SMB session.

Thanks so much for looking at this.

Unfortunately that set of problems was not related to my playback problems. What you found for July 1 was an attempt to copy some media from the UNRAID to an old WHS server (192.168.0.235) for safekeeping.

The WHS server was very intermittent and finally failed completely and shut down (My guess is the power supply needs to be replaced).

My media playback problems happen on at least 2 clients a Dune player and VLC on a Windows desktop. I MAY also see similar problems copying data from UNRAID to different destinations (not playback rates).

Since the debug data may track problems I will use UNRAID as my playback source for a few days.

Possibly not relevant but in the thread ;

https://forums.unraid.net/topic/198661-how-can-a-revert-back-to-724-after-upgrading-to-725/ there is a report that dropping back to 7.2.4 from 7.2.5 fixed a similar problem.

Lots of differences (I am running 7.2.3 my player is based on non-Nvidia chips etc.) and since I have a clean install not sure if I can drop back if there is no "back" so my guess is this is not relevant.

Anything I can do to provide additional information?

Again thank you!

Post the approximate date and time you last experienced the issues to see if there's anything logged.
