[Ganglia-general] gmetad.conf for large number of nodes

[randy <ran...@co...>]

I'm trying to configure ganglia (3.0.7) to monitor 120 nodes. It works 
fine if I just enter a small number of nodes as data_source in the 
gmetad.conf file, just like all the documentation shows. But if I try to 
enter "too many" nodes, gmetad segfaults at startup.

That is,

data_source "cloud" rack1node1 rack1node2

works just fine.

But a data_source entry with all 120 nodes listed segfaults. I've also 
tried using a backslash-newline to break the line apart with the same 
result. My last attempt used multiple lines, all with the same cluster 
name ("cloud"). I have about 10 lines like that, as many as it took to 
list all the nodes. That doesn't segfault, but it only shows some of the 
nodes (the last 30, which span multiple data_source entries).

Admittedly it was Friday afternoon when I tried this, so I didn't spend 
too much time debugging. But it's been bothering me all weekend. I 
haven't seen any examples/docs with more than a couple nodes listed.

Thanks for any help.
