packets collapsed in receive queue due to low socket buffer

[Ergin Ozekes]

Hi all;

My current working network bandwidth is 350 Mbps.
My netstat -st output prints out below value increasingly.

    1555903887 packets collapsed in receive queue due to low socket buffer
    1555908175 packets collapsed in receive queue due to low socket buffer
    1555912925 packets collapsed in receive queue due to low socket buffer
    1555920054 packets collapsed in receive queue due to low socket buffer
    1555929162 packets collapsed in receive queue due to low socket buffer
    1555938162 packets collapsed in receive queue due to low socket buffer
    1555945682 packets collapsed in receive queue due to low socket buffer
    1555951783 packets collapsed in receive queue due to low socket buffer
    1555959318 packets collapsed in receive queue due to low socket buffer
    1555962474 packets collapsed in receive queue due to low socket buffer
    1555969574 packets collapsed in receive queue due to low socket buffer

I've increased to socket buffer size, backlog queue size and memlock value
was set to unlimited for ats user. How can I fix it completely?
BTW, How can I increase read from socket(connection) performance of the ATS?


Best Regards,
