[erlang-questions] is there anything wrong with global?

[289602744]

These days,I found global did not work well.
I have hundreds of nodes,and these nodes are connected with each other.
But on some nodes, I can't get a process's global registered name with global:whereis_name, althrough I can get the node info by net_kernel:node_info/1
I didnot find a way to resolve this problem. Unless I unregister that process's name and then register the name again, and then, I can get the global name by global:whereis_name/1.
Is there anything wrong with global? with so many nodes, I can't unregister and then register a process name every time I find global return me an undefined.
