We have session resumption enabled (lifetime 24 and max_entries 8192) 
and we do not have any problems:

Only restarted on the 14th as I was adding a new configuration tweaking 
(that nice rlm_replicate bits for eduroam accounting proxying) but our 
setup can run for weeks with no memory leak woes.  Ages ago we did have 
a rlm_detail related memory leak but I think that was fixed in 2.1.11.

The extra high memory usage on ours is probably related to the rlm_perl 
instance[1].
