Lot of errors recieving the streams - LAN card ?

Recommended Posts

Hi,

Recieving ~30 channels mostly in UDP and retransmitting to HLS.

Periodically have errors on random channels like:

UDP input related errors are mostly
[TV1_Program1 i/1] UDP recv buffer overflow
 
or
HTTP related input errors are mosly
[YLE1_Hls i/1] Bitrate:1726Kbit/s PES:9 CC:1
[YLE1_Hls] Channel has no active inputs
Tuned the network kernel limits related to the astra wiki, tried to double the wikis limits, no help.
 
netstat -suna
 
IcmpMsg:
    InType3: 1357
    OutType3: 8
Udp:
    853419015 packets received
    8 packets to unknown port received.
    50491 packet receive errors
    1530543246 packets sent
    RcvbufErrors: 50491
    IgnoredMulti: 17844

 
The LAN card is:
 RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
 
Tried another RTL card, the same problems.
 
Please help to understand the problem comes from incompatible HW or wrong SW tuning ?
 
Can it be the LAN card ring buffer issue and changing to intel + increase the ring buffer sove the issue?
 
We are using the latest v5.64 Licensed Astra.
 
Kind Regards
 
Aleksander

Thanks, we will try to play with the buffers and also ordered Intel network cards cause rtl we cannot change the ring buffer size.

 

Kind Regards
