Indeed.  It did only start to happen once I upgraded to 2.1.11 from 
2.1.10.  Of course I was originally plagued by the OP's problem of the 
memory leak when using git v2.1.x between these releases; which might 
have hidden this particular problem.
Before 2.1.11, FreeRADIUS ran fine for weeks.

...plenty though.  Over nearly 12 hours of use, RAM usaged for 
FreeRADIUS is still at 15MB for one of my nodes and the other is 17MB.  
Linux is using the 280MB for filesystem cache and still has 180MB free!

If you think there is something relevent in v2.1.x since 2.1.11 then 
I'll give it a go sooner rather than later.

Can you think of something that might not be system RAM related but 
maybe caused by another possible RAM limit, heap, stack whatever it is 
(not quite my forte)?
