I have 8CPU/24gb RAM in my Linux servers around 30+. All the servers are running with Java based application with NFS mounted.
The problem what I have is, When I reboot servers the server memory looks decent. But after some time the "cached" memory increasing and "free" memory getting reduced and reaching some mega bytes. I searched in various forums that it is behavior for RHEL and there wont be any performance issue. But I see better performance when there is more memory available in "free". The same performance goes down when the "free" memory reach 300mb.
I need your expert advice why the cached memory is increasing.. and how I set threshold so that I will always have 1-2gb free.?

nfsd
NFSD(8) BSD System Manager's Manual NFSD(8)NAME
nfsd -- remote NFS server
SYNOPSIS
nfsd [-6rut] [-n num_threads]
DESCRIPTION
nfsd runs on a server machine to service NFS requests from client machines. At least one nfsd must be running for a machine to operate as a
server.
Unless otherwise specified, four servers for UDP transport are started.
The following options are available:
-r Register the NFS service with rpcbind(8) without creating any servers. This option can be used along with the -u or -t options to
re-register NFS if the portmap server is restarted.
-n Specifies how many server threads to create. The default is 4. A server should run enough threads to handle the maximum level of
concurrency from its clients.
-6 Listen to IPv6 requests as well as IPv4 requests. If IPv6 support is not available, nfsd will silently continue and just use IPv4.
-t Serve TCP NFS clients.
-u Serve UDP NFS clients.
For example, ``nfsd -t -u -n 6'' serves UDP and TCP transports using six threads.
nfsd listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC
1094 and NFS: Network File System Version 3 Protocol Specification.
The nfsd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO nfsstat(1), nfssvc(2), mountd(8), rpcbind(8)HISTORY
The nfsd utility first appeared in 4.4BSD.
