[OpenSIPS-Users] [OpenSIPS-Devel] Are accounting radius requests syncronous?

[Adrian Georgescu]

Alex,

This has been discussed many times over. We are aware about this  
problem, which will be addressed by a new server design that will be  
non-blocking not just for radius but for any other potentially  
blocking operation. Check the mailing lists for this issue so that we  
do not put another nail in the same closed coffin.

To solve your problem before we get to the new design you can use a  
radius proxy that absorbs the delays and retransmissions upstream to  
the real server.
