[Linux-cluster] Again DLM messages and high load



WE are using:
 GFS         : CVS 1.0.3 stable
 kernel      : 2.6.17.11-sara1
 NFS-daemons : 128
 GFS-servers   : 5

This node was the master and when this message was displayed, the load will rise to the number of NFS daemons and nfs does not work more. We had to reboot the node:
 Oct 25 03:12:31 ifs4 kernel: dlm: lisa_vg5_lv1: cancel reply ret 0
Oct 25 03:12:31 ifs4 kernel: lock_dlm: unlock sb_status 0 2,a45325d flags 0 Oct 25 03:12:31 ifs4 kernel: dlm: lisa_vg5_lv1: process_lockqueue_reply id a50a027c state 0

I had to reboot the master node (ifs4) when the node went down the other nodes re-elected another master. 3 nodes use the same master and on one node has another master. Is this oke?:

node 1,2,4
Fence Domain:    "default" 1   2 run       - [5 2 1 3 4]

node 3:
Fence Domain:    "default" 1   2 run       - [2 5 1 3 4]

cman_tool nodes is the same for all nodes.


Regards
