IMO you blame the wrong people. You can have the same kind of problems
with any Illumos-based distribution if you activate a zone and let the
machine just sit there for a week or so or have a lot filesystem
activity using mmap(). Either way the machines will choke themselves
to memory starvation. The only workaround we found are regular reboots
(every 24h), or limit the ZFS ARC to an absolute minimum.
