The current implementation is just a placeholder. The output should
probably go into its own log file but I let Seth figure that out. :-)

Yes, these are BroObj's Error() etc. methods; I just removed the
methods in the util.h. Generally, I left object-specific error methods
in because (1) they sometimes do additional things, and (2) it would
have required touching lots of places without making things much
But: these methods used to call error() for doing their output and
*that* has been replaced with Logger::Error().
Let me know if you still find a method logging errors directly to
stderr/out (except for debugging stuff, I didn't touch that, like in

Can't think of anything.

Hmm, that's right. I forgot that we aren't limiting how many events we
process each time we drain the manager (we do limit timers per
packet). Seems that should be caught and errors reported in a
log_error hanlder be written out to stderr.
Another question: what do you guys think about merging Logger and
LogMgr now? I.e., let LogMgr do both error reporting and normal log
