The sunstone_stats_svr process is the one which inits the stats shared mem.  After the shared mem is init'd then the clients can bind.  Before the stats shared mem is init'd client can't use stats.

But all other client which tried to bind after the sunstone_stats_svr comeup, succeed as seen below.

I think we need to introduce some re-tries with sleep in the dpc_rm_svr so that the bind goes through.
