recommended loglevel setting (2.0.11)?

[Peter W <peterw@usa.net>]

Folks,

I'm trying to figure out a good setting for loglevel for OpenLDAP 2.0.11 for
production use. Ideally I'd only like to see errors and unusual events, like
slapd starting and stopping. But none of the 2^0 - 2^11 (1 - 2048)  
additive choices listed in the slapd.conf man page suggest what I want. And
loglevel of 0, of course, doesn't seem to log anything. :-(

Is there a loglevel that records only stops/starts/exceptional errors?

Thanks,

-Peter
