Both of those error can occur if memcached is not running.
To make sure that memcached is running and configured properly check
the output of `ps ax|grep memcache` and verify that the port and host
listed there match the settings in the <cache> section of
/openils/conf/opensrf.xml.
Memcache is running, and seems to be configured correctly.
~# ps ax|grep memcache
