i have a issue in manging cahce memory utilisation on my redhat linux 8.0 .the server have the following software installed in it
dual xeon processor /2 gb ram / 72 GB SCSI HDD
after the fresh reboot of the system free memory will 1.7 gb buffer usage 45mb, cache 80mb
and other systm process using the remaining memory. but if we running the server for two to three days , the cache memory usage will be around 1.6 gb , remaing is occupied by the java,apache, mysql .now the server showing only the 12 mb free space.
i dont know why the cahce memory usage is very high, and i know that , after certain period of system run , it should be freed by the OS.is there any problem in linux kernel, any measures to be taken to control over the cahe memory usgae. Or is there any tunning to be done in the server.
