I already am running 8.3.1 [ i mentioned in subject]. I am having the default settings for those. can you pl. share the settings for check points: current settings all default #checkpoint_segments = 3 # in logfile segments, min 1, 16MB each #checkpoint_timeout = 5min # range 30s-1h #checkpoint_completion_target = 0.5 # checkpoint target duration, 0.0 - 1.0 #checkpoint_warning = 30s # 0 is off
