Hi Marc,

OpenSER could not allocate shared memory to save the AVP value. The reason 
could be a low memory condition because of overload, or a memory leak. If 
this is a low memory condition, then you could try to increase the shared 
memory size. 

Does this error occur in a production environment with real load, or at your 
tests?

I did a short look in the auth_radius module, the error condition that happens 
here is not handled. I'm not sure if this is correct behaviour.. 

Cheers,

Henning
