Package: nfs-kernel-server
Version: 1:1.1.2-6lenny1
Severity: important

I am using nfs-kernel-server with Kerberos authentication to export 
/home to a cluster of over a thousand nodes. While nfs-kernel-server is 
running, memory usage goes up indefinitely on the NFS server. After 
several days, the system crashes with a kernel panic due to being out of 
memory. If I stop nfs-kernel-server, memory usage appears to go down 
slowly. I tried the patch in bug #513284, but memory usage did not seem 
to stop growing. Below is my /etc/exports:

  /srv/nfs      gss/krb5i(insecure,nohide,no_subtree_check,root_squash,rw,sync,fsid=0)
  /srv/nfs/home gss/krb5i(insecure,nohide,no_subtree_check,root_squash,rw,sync)

Will be happy to provide further information.

I guess it didn't work out.  Closing since it's not clear how to move
forward on this, lenny has reached its end of life, and I have a vague
hope that squeeze might have fixed it anyway.  Please don't hesitate
to write if you end up learning more, though, so we can make sure
later releases don't have the same bug.

Thanks,
Jonathan
