No errors anymore? Did you reduce the number of parameters as Digimer 
suggested? Then it would be maybe interesting for others to see your 
working fence configuration as configured inside cluster.conf.

I would suggest to test a little bit too much than doing not enough 
testing ... ;-) ... debugging afterwards is more costly than doing 
testing before ...

So my recommendation would be to test that manually started fencing, 
too, to see whether any messages/errors appear.

After that you are probably fine ...

Kind regards,
