A user in #fedora got bit by this where his rsyslog was upgraded but not his libfastjson. Updating to libfastjson-0.99.7 allowed rsyslog to startup and begin logging. But it appeared to die quickly. This happened at least twice. There could be other things going on with his setup, but I thought I'd point out a potential issue to be on the lookout for even if the missing symbol has been resolved.
