interleave=3Dtrue=8Awhich is I think the desired setting, i.e. Only wait fo=
r
the local instance rather than all the clones. I've tried with
interleave=3Dtrue & false=8A doesn't seem to be cause of the problem.

I'll continue with interleave=3D"true" on all clones.

I've been playing around with ptest and it I think the fs1_group is being
restarted, which in turn restarts NOSFileSystemCluster etc.
