Failed to update header with correct filesize

[Koze]

Hi,
I am using following command to re stream rtmp or http:

ffmpeg -re -i rtmp://85.10.217.218/live/eurosport -codec copy -bsf:a aac_adtstoasc -strict -2 -flags +global_header -f flv rtmp://live.xxxxxxxxxxxx

Each time after about 20-30 minutes I am getting following information:

[flv @ 0x29fc7e0] Failed to update header with correct duration.
[flv @ 0x29fc7e0] Failed to update header with correct filesize.

I use Google for last couple of days but could find solution.

I would appreciate any suggestions or help how to resolve this issue.

Thank you in advance
