Question regarding clustering

Hi

We have setup a ejabberd cluster with 2 nodes. The routing of messages from one node to another node works fine. However we see that there is a problem with ejabberdctl commands when one of the node goes down and comesback. The error is seen on the node which is still running.

Problem 'exit {aborted,
                  {no_exists,
                      [ejabberd_commands,
                       [{{ejabberd_commands,'$1','_','_','_','$2','_','_',
                             '_','_','_','_','_','_','_'},
                         [{'==','$1',{const,list_cluster}},
                          {'=<','$2',{const,1000000}}],
                         [{{'$2','$_'}}]}]]}}' occurred executing the command.
Stacktrace: [{mnesia,abort,1,[{file,"mnesia.erl"},{line,313}]},
             {ejabberd_commands,get_command_definition,2,
                                [{file,"src/ejabberd_commands.erl"},
                                 {line,392}]},
             {ejabberd_commands,get_command_format,3,
                                [{file,"src/ejabberd_commands.erl"},
                                 {line,360}]},
             {ejabberd_ctl,call_command,4,
                           [{file,"src/ejabberd_ctl.erl"},{line,318}]},
             {ejabberd_ctl,try_call_command,4,
                           [{file,"src/ejabberd_ctl.erl"},{line,298}]},
             {ejabberd_ctl,process2,4,
                           [{file,"src/ejabberd_ctl.erl"},{line,247}]},
             {ejabberd_ctl,process,2,
                           [{file,"src/ejabberd_ctl.erl"},{line,225}]},
             {rpc,'-handle_call_call/6-fun-0-',5,
                  [{file,"rpc.erl"},{line,206}]}]

After debugging further we found that this could be because of the the table ejabberd_commands being replicated across the nodes. Is there a problem for this issue? Does this table even needs to be replicated as this is more of static content which is being stored.?

Thanks in advance.
