Comment 14 for bug 1405998

So my very simple-minded analysis suggests that we are doing something in MAAS which causes us to run out of FDs, possibly one of the issues for which we have a traceback above (such as the one with find_mac_via_arp() in its stack). This may be an FD leak or perhaps just the result of us trying to do too much at once, such as trying to query power status -- or something else.

As we run out of FDs we then crash in other places where new FDs are requested, finishing with the failure to generate an OOPS because that itself requires an FD, which then triggers recursive OOPS generation.
