>Description:
I have two machines i386 as NFS clients
I have 7.1 before and today upgraded to 7.2-RELEASE-p3 but as for me problem hasn't gone.
Periodically on both servers I getting

kmem_map too small with panic
and I chaned all needed parameters to turn it...No result

vmstat -m | grep nfs    showing me 

nfsclient_diroff     1     1K       -        1  512
nfsclient_req     0     0K       -   121469  64,128
nfsclient_nlminfo 388399 12138K       -   388399  32
nfsclient_lock     0     0K       -   388399  512


and this 12138K always growing right after it will get max memory for kernel and it will be panic I think...
I thought after update it was fixed but not... :-(

 
>How-To-Repeat:
Don't know
In fact NFS clients and lot of requests to NFS-server?..
