ROCK stability problems

Support
1

Roon is great when I can keep it up and running.

5th Gen i7 NUC (128 SSD, 16GB)
SMB share to QNAP TVS-463 SMB share
Squeezebox Receiver, iDevice and Win7/10 endpoints
Network consist of trunked Netgear GS752TSBs under an Untangle firewall with a NVG599 Uverse box on top.
Wifi is a trio of Ubiquiti Unifi “enterprise” looking discs. All other network usage appears to be stable, even when the whole house is streaming Multicast video to their own devices.

Have reinstalled ROCK x2 and rebuild the DB (single folder). No luck.

Here are the final drops in the last 4 crash logs as found in Data/RoonServer/Cx

Please tell me I have an illegal character in an ID3 tag or something else as pointlessly pernicious.

Thanks,

Managed Switches have been known to cause issues. Check to see if Jumbo Frames (Should be OFF), Flow Control is ON, and I being two of the main culprits for issues.

Switches were not on flow control. Worked well for around 6 hours (big improvement). Further investigation found a locked up NAS.

I’m opting to move the flacs to a usb drive to eliminate directory based network issues next.

Any further advice appreciated.
