Roon 1.6 (Build 401) - Server crashing after ~10 min due to "Continuum One - Qua Continuum" [Ticket In]

Support
1

Shortly after upgrading to Roon 1.6 (Build 401), I started experiencing Roon Server crashes after playing (10-12) min of music. This has been recurring persistently, independent of the type of music played (DSD, 24-96, 16-44); or playback (direct USB to DAC, Airport Express, NAIM). Music sources include local library, ethernet to NAS, and also Tidal streaming.

I’m running Roon on a Windows 7 server, with primary listening via USB to a Mytek Manhattan DAC,
recently updated to firmware 2.20. Secondary listening areas include Airport Express, and NAIM.

Error Msg:

Roon has stopped working

A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution
is available.

Wireshark seems to show some degree of TCP retransmissions between the NAS and the Roon
Server; but overall connectivity seems to be fine:

Fun … while writing this up, I’ve experienced another Roon Server crash, with NO music playing.

Hi @Sean_Finn,

Apologies for the trouble here! I was hoping for now you could use the directions found here and send us over a set of logs using a shared Dropbox link. Once we receive the logs I’ll be sure to pass them over to the technical team for review.

Thx … do you have a direct upload option?

Hi @Sean_Finn,

Thank you for your report here.

We are actually in the process of investigating that specific file Continuum One - Qua Continumm as it has been reported by other users as well to be causing issues in Roon (see this thread).

A ticket has been raised with our dev team and as soon as we have more information to share Dylan or I will be sure to let you know!

Thanks,
Noris
