I'm running 3 http server with nothing fancy on them. it's just apache with a shared directory via SSHFS, looking at the usage of RAM I can see that portmap is using quite a bit of RAM/CPU and I have no idea what it's doing.

     |      `-sshd---sshd---bash---pstree

Do you think I can safely stop/purge it?

If you don't use NFS, yes, it's safe to remove it.

I disabled portmap on each server and apparently it's all good. thanks – sathia Jul 30 '12 at 15:48
There is no relation between sshfs and nfs. – diegows Jul 30 '12 at 16:04
Having the portmapper running and ignored is also a potential security risk, so I'd disable it unless absolutely required (like any other service). – XTL Dec 3 '12 at 14:41
