Goed morning,

How can I then increase opensips’s internal queue size?

Best regards, Johan

The `drop_requests` statistic is incremented when:
* the request is dropped by a pre-script callback (like B2B when there is no script execution for certain messages)
* the stateless `forward()` core function failed to send out something.

No I don't.
what I find strange is that MAX_RECV_BUFFER_SIZE 262144 is the default value of net.core.rmem_max and net.core.rmem_default.

    Are you calling drop() anywhere in your script?

    would it make sense to recompile with other flags ? And how do I
    set them  (I don't find these of menuconfig's compile options)?

    Currently it has MAX_RECV_BUFFER_SIZE 262144 and BUF_SIZE 65535.

    Can somebody explain also what both flags mean.

            Guys,

            I have an opensips instance running with 24 worker children.

            The worker load is very low.

            UDP queues are on 50 megs.

            when i query via the OS

            cat /proc/net/udp

            => no drops

            what worries me is that there are drop requests and they 
            go up when I query via the mi interface

            opensipsctl fifo get_statistics drop_requests

            core:drop_requests:: 198107

            opensipsctl fifo get_statistics drop_requests

            core:drop_requests:: 199157

            opensipsctl_reg fifo get_statistics drop_requests

            core:drop_requests:: 204116

            I don't see any memory issue, also the processload is low.

            so 3 questions:

            - what exactly is drop_request.

            - do I need to worry about this

            - how can I make them go lower.
