[OpenSIPS-Users] Packet Loss and its Solution

[Bogdan-Andrei Iancu]

Hi Faisal,

Let me comment a bit on the loss at software - packages can be discarded 
at TCP/IP stack level (by kernel) if no application is reading the data  
(or no reading as fast as the data comes).

You can check on this (if opensips is able to process all incoming 
traffic, without having the kernel to discard data because of full 
buffering on sockets) via some statistics from the NET class :
         http://www.opensips.org/Resources/DocsCoreStats17#toc17

An overall idea over the load in opensips (if you have idle processes or 
not) can be monitored via the LOAD stats:

Regards,
Bogdan
