What I suggested to the original poster was that *he* checks
whether *his* server leaks a really significant amount of memory
-- and starts to try a (difficult) memory leak analysis only in this
case. If he can restart his server periodically, this may make
the analysis unnecessary.

I also reported that I have undertaken such an analysis several times and
what helped me in these cases. I know - by experience - how difficult 
those analysis are. And there have been cases, where I failed despite
much effort: the systems I work with are huge, consisting of
thousands of components, developed by various independent groups,
using different languages (Python, C, Java); each of those components
may leak memory; most components are "foreign" to me.
Surely, you understand that in such a context a server restart
in the night of a week end (leading to a service disruption of a
few seconds) seems an attractive alternative to trying to locate the leaks.

Things would change drastically if the leak is big enough to force a restart
every few hours. But big leaks are *much* easier to detect
and locate than small leaks.
