[Ocfs2-users] What's this: dlm_controld[xxx]: xxx cpg_dispatch error 9

[eric]

Hi list,

When running ocfs2 test cases, I   usually see this error in message 
file while
testing goes well. Error message below:

  Sep 24 22:43:03 m1 dlm_controld[1897]: 191602 cpg_dispatch error 9

It always appears around "mount" and "umount". Is this normal?  Or what 
happened?
Any hints would be appreciated!
