In my network STB generates IGMP Leave (in STB logs "End of Stream") without any reason or there is something what I don't understand.
There is one exeption STB directly connected to PIM (ASR920) working fine only errors I find in logs are "TS Continuity Counter Error".
All others STB connected to switches behind PIM experience in logs "STBPlayer: End of Stream". Dump from tcpdump shows only "IGMP Leave" and after second STB rejoin multicast group with "IGMP Membership Report". It happen in random time, random vlans and the problem intensifies in the evening. Whe have we have enough bandwidth. I check every counter what I know in PIM (asr920) and didnt't find any errors, drops, misses, failures, etc.
In addition mu;lticast group UPTIME in PIM coincides with the time when STB has left the group itself.

Behind ASR920 is N3K-C3064PQ-10GE then DCN,DLINK and other vendors.
PIM ASR920 use sparse-mode and igmp snooping v2

What could it be? How can I identify the source of the problem?
