I’ve done quite a bit of digging on this and have found no topics discussing this behavior. The closest I’ve found is this unanswered thread Client’s stop downloading layouts
I have an android display that’s been working fine until approximately the last week or so, which is now failing to complete the ‘layout’ download of layout that have (or have had) an mp4 attached to it. I have not yet been able to due extensive testing if the media type has an impact on behavior beyond that described above.
When a layout with larger sized mp4s (tested between 7MB & 211MB) are scheduled, the Layouts download pane (of the manage display page) continues to show an increasing number for the scheduled layout, beyond that of the size of the layout (currently it reports two hundred thirteen point four two (213.42) KiB downloaded of two point six three (2.63) KiB layout size. Changing to a different layout without video works as expected. Adding videos to that layout cause the behavior described above. In the Media pane of the manage display page, all associated videos are listed as pending download unless the media files are explicitly assigned, in which case they display similar behavior to that of the layout. The Bandwidth statistics represent this behavior as well reporting ~22GB of “Get File” transfer within the last week, which is unreasonable given this is only an 8GB device and the size of the layout content that’s being scheduled. I’ve also confirmed that these layouts work as expected on other displays of the same device model.
Logs and Display Management Details
In the logs, I have been seeing the following error, but I believe this to be unrelated since it was showing up before this problem started occurring. Not sure if it’s pointing to a different issue though since it doesn’t report what device or source IP it’s associated with.
