Operating Systems Linux Red Hat Memory problems in NFS client server Post 302635191 by mark54g on Friday 4th of May 2012 11:07:53 AM
In the output of the commands I gave you, look to "Active Memory"

This is simply the memory being actively used by the OS and applications. If you dropped your cache, you did not get any free memory back. The memory was always available if you needed it.

Caching is not dangerous. Otherwise network traffic gets to be a burden.

NAME
dfmounts_nfs - display mounted NFS resource information SYNOPSIS
dfmounts [ -F nfs] [-h] [server...] DESCRIPTION
dfmounts shows the local resources shared through NFS, along with the list of clients that have mounted the resource. The -F flag may be omitted if NFS is the only file system type listed in the file /etc/dfs/fstypes. dfmounts without options, displays all remote resources mounted on the local system, regardless of file system type. The output of dfmounts consists of an optional header line (suppressed with the -h flag) followed by a list of lines containing whitespace- separated fields. For each resource, the fields are: resource server pathname clients ... where resource Does not apply to NFS. Printed as a hyphen (-). server Specifies the system from which the resource was mounted. pathname Specifies the pathname that must be given to the share(1M) command. clients Is a comma-separated list of systems that have mounted the resource. OPTIONS
-F nfs Specifies the nfs-FSType. -h Suppress header line in output. server Displays information about the resources mounted from each server, where server can be any system on the network. If no server is specified, the server is assumed to be the local system. FILES
