[SR-Users] RTPProxy Issues

[Maxim Sobolev]

Yes, that's probably it. There should be also some error in the log that
rtpproxy emits, so you might want to check that. I see people run into this
from time to time, perhaps we need to check and put out a big warning in
red if the OS limit appers to be too low?
