It sounds almost as if there are two backends for the objects, one in memory and one \
database... but your configuration certainly doesn't show that. Have you bumped up \
core debug (debug to console in logger.conf and core set debug 9) and looked to see \
if anything stands out?

There is no cache or memory mechanism built into sorcery that is always there, so I'm \
not sure where it'd have two objects stored or where to look. The "pjsip show \
endpoints" command just asks the sorcery backends to return the data they have, for \
example.
