Debian openSSI 1.9.1 issues

We are testing openSSI as the platform for our computational cluster.  
It is based on a HP DL140 blade server with a total of 10 nodes.  Each 
blade has two 3.2 GHz Xeon processor and 2Gb RAM.  Currently there are 7 
nodes with node 10 as the root node.  The home directory is on an NFS 
share.  The use of software RAID on the two IDE drives of the root node 
required editing the initrd image (in order to include the necessary 
modules and scripts) to make the machine bootable.

We have faced some additional issues and would appreciate any assistance 
in resolving them.

1.  the nfs client appears to have some trouble establishing the 
connection with the server.  Syslog has the following repeated 5-6 times:

Apr 19 12:13:04 plbscc04 kernel: RPC: failed to contact portmap (errno -5).
Apr 19 12:13:04 plbscc04 kernel: lockd_up: makesock failed, error=-5
Apr 19 12:13:39 plbscc04 kernel: portmap: server localhost not 
responding, timed out

portmapper and lockd don't seem to be running.

2.  Some of the nodes go down and we can't figure out why.  Syslog also 
has the following message:

Apr 15 15:42:59 plbscc05 kernel: OpenSSI: Node 4 has gone down!!!
Apr 15 15:43:04 plbscc05 kernel: Assertion failed! vma->vm_pgoff == 
pgoff, cluster/ssi/vproc/as_xscribe.c, as_do_vma, line=987

Is the node going down connected to the message regarding vma...?

3.  Is there an updated 1.9.2 version of debian packages that will solve 
these?

Thanks,
Venkat
