Memory problems in NFS client server
Hi all,
i have some doubts in a situation that i fail to get an answer in Google.
I have a solaris 10 nfs server and 5 centos 6.0 nfs clients.
The problem/situation is that in the clients the free memory is "disappearing" along the time (passing to used)..and it gets free if i umount the nfs mount point. I can see also that the speed that the memory is "disappearing" is related to the use of the nfs fs (3 of the 5 servers use the nfs fs more intensively and in those it disappears faster).
I m mounting with:
rw,vers=4,hard,rsize=32768,wsize=32768,noac
Kernel version:2.6.32-71.el6.x86_64 and 2.6.32-220.13.1.el6.x86_64 (i have updated in one server to check the behavior and its the same)
and:
rpm -aq | grep -i nfs
nfs-utils-1.2.2-7.el6.x86_64
nfs4-acl-tools-0.3.3-5.el6.x86_64
nfs-utils-lib-1.1.5-1.el6.x86_64
and in the updated server
nfs4-acl-tools-0.3.3-5.el6.x86_64
nfs-utils-lib-1.1.5-4.el6.x86_64
nfs-utils-1.2.3-15.el6.x86_64
By the way i m checking the memory with the free -m command in this line:
...
-/+ buffers/cache: 480 3286
...
(i did a umount/mount some time ago so now its not bad, but in couple of days it gets the opposite or worse..)
Can someone give me some lights about this behavior?
Thanks
