Do the Buffer full messages indicate a problem?
If so what can I do about it?

Also, what does the tag [WRN] in the log refer to?

#2

It indicates your disk is not fast enough, or you're running out of CPU or RAM

#3

The CPU is an NVIDIA Shield with an external Seagate 5 TB One Touch drive.

Should this configuration cause buffer problems with 3 tuners active (2 recording shows and 1 live viewing)?

Also, why am I activating an additional tuner for viewing when the channel viewed is the same as the channel recording and I set Tuner Sharing to ON?

#4

Which version of android OS on the shield?

What file system is the drive formatted using? We have seen similar issues when using NTFS instead of exFAT

Can you submit diagnostics from your dvr

#5

Warning

Tuners are listed in a different order in the app vs dvr

#6

NVIDIA Shield v9.0.0(33.1.0.236)
Drive formatted as exFat

#7

Diagnostics please

We're you using the same hardware before 9.0? And it was fine before?

#8

It was working OK before v9 update. However I added an HDHR FLEX after the update. You will notice in the log that it's the FLEX that is showing buffer problems.

I sent the diagnostics you requested:

bc1edc3b-0cff-4abc-83d6-c2473bf8d811

#9

Are you continuing to see this? Seems like maybe the SHIELD update made disk performance worse.

#10

I still get occasional buffer warnings. the major problems with access permissions on the Shield have been resolved.

I currently use the shield to run other apps besides the Channels Server and DVR, apps like Netflix, HBOMAX, Amazon Prime etc. Would it be helpful to the buffer issue if I dedicated the Shield to Channels apps only, by removing those other apps from the Shield and running them on the SmartTV instead?

#11

No none of those apps would be touching your external storage.

#12

Got it. Thanks
