Two servers running OpenLDAP in master/master using syncrepl, roughly once per
week one of the servers stops responding to new connections, I tried logging
with loglevel=1 and this is all I got, all suggestions and comments
appreciated.
This is most likely a "load" related problem since we never experience this
problem in the testlab, only production.:
