DSM resets max RAM to … well, less than available

Hi,

I've been trying to set mem\_max\_mb in /etc/synoinfo.conf to the actual installed memory in my DS218+ running DSM 7.2 : one 8192MB DIMM + the original 2048MB DIMM , hence **10240** MB.

However, upon reboot, the value there has been reset to **6144** . Yup, no idea where that number comes from.

DSM seems to use up to about 3GB and the remaining of the 10GB are used for cache, according to Resource Monitor. So, I don't know if that's really an issue per se.

Has anyone observed this and got an explanation ?

Thanks :)
