The main web interface is my concern. Gmetad sucks up memory like it's free, and the disk I/O created when rrds are updated quickly get out of hand. Because of this we had to move the rrds to a ramdisk, which eats up even more memory.
I was wondering how you back up those RRDs while Ganglia is running since from what I remember gmetad seem to keep quite a bit of things in the memory.
BTW you can try using tmpfs instead of ramdisk. It is similar to ramdisk however it can/will swap out any files that are not being used. Plus it only uses the space if you actually copy files into it.
