[Wadii ELMAJDI | Evenmedia]

Calling exit() during the initial request and right before creating the dialog also increments the drop_requests statistic

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.
