restarting every night?

Which memcached version? Which system architecture (AMD64, etc.)? Which
libevent version? If you were running it on a 64-bit architecture, was it
compiled as a 32-bit app or a 64-bit one?
Our memcached instances are all 13GB and they all run until we have to take
the machine down or install a new version. We compile in 64-bit mode and
memcached happily chews up all the memory we throw its way.
