nfsmapid issue

Hi, we have Solaris zone servers configured with solaris 10. nfsmapid uses 1 GB memory. we have NFS filesystems available on this server.

can anyone guide best practice to resolve this issue.

I searched man page nfsmapid.

nfsmapid caches a user's UID and GID. If a user subsequently
changes a UID or GID, using one of the utilities listed
below, the nfsmapid cache becomes stale. At this point, any
NFS operation that gets or set attributes will result in the
exchange of this stale information. To resolve this situa-
tion, restart nfsmapid, as follows:

# svcadm restart svc:/network/nfs/mapid:default

Thanks .. awaiting your response..

nfsmapid(1M)						  System Administration Commands					      nfsmapid(1M)

NAME
nfsmapid - NFS user and group id mapping daemon SYNOPSIS
/usr/lib/nfs/nfsmapid DESCRIPTION
The nfsmapid daemon maps to and from NFS version 4 owner and owner_group identification attributes and local UID and GID numbers used by both the NFS version 4 client and server. nfsmapid uses the passwd and group entries in the /etc/nsswitch.conf file to direct how it performs the mappings. The nfsmapid daemon has no external, customer-accessible interfaces. You can, however, administratively configure nfsmapid in one of the following ways: o Specify the NFSMAPID_DOMAIN parameter in nfs(4) o Specify the _nfsv4idmapdomain DNS resource record. Please refer to the System Administration Guide: Network Services for further details. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWnfscu | +-----------------------------+-----------------------------+ SEE ALSO
svcs(1), automountd(1M), mount_nfs(1M), svcadm(1M), share_nfs(1M), nfs(4), attributes(5), smf(5) System Administration Guide: Network Services NOTES
The nfsmapid service is managed by the service management facility, smf(5), under the service identifier: svc:/network/nfs/mapid Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. If it is disabled, it will be enabled by mount_nfs(1M), share_nfs(1M), and automountd(1M), unless its application/auto_enable prop- erty is set to false. This daemon might not exist in a future release of Solaris. SunOS 5.10 18 Nov 2004 nfsmapid(1M)
