`atop` shows that `carbon-relay` is eating 80, 90% USRCPU. From the
I don't know about anyone else, but I don't know what carbon-relay is. A quick google suggests it's part of that graphite monitoring/RRD replacement thing; which version are you running (Or: what reactor is it using)?
How many open files do you have?
`strace`:
Without timestamps it's difficult to interpret this unambiguously; that could be a microsecond or minute we're seeing ;o)
The strange thing is: even restart the service, it seems stuck at fd 7 everytime running `strace`. Does it mean this fd is not being cleanup properly?
No. fd numbers are allocated starting from 0 and going upwards. The same process running the same startup code every time will tend (not always, since it's order-dependent) to use the same file descriptors for the same things, modulo close/open events.
