I'm serving on Images ( JPG|JPEG|PNG ) from an apache server. after sometime, the system cache becomes sooo populated that no other programs are able to run -- like recently I noticed that one of the php Cronjob got terminated because of no memory available to process a large number of files.
Can I configure apache2 in such a way that the images served aren't cached in RAM at all, and they should go directly form the storage subsystem. I know it will increase IO, but System will be able to perform other functions.
Secondly, as far as I know, these caches are circular in their operation. whenever there is need for some RAM space, older ( LRU? ) objects are kicked out of the RAM and needy programs gets inserts. I'm not seeing it happening here.
Its a Debian-8 Linux System, running Dell-R320 with 24 Cores + 15GB RAM. all filled up sooner or later.
