log buffer space. Wait for space in the redo log buffer in SGA. Solution. Increase log_buffer parameter in init.ora. Above 3M log_buffer little affect, if still a problem then backup is at disk level. Improve disk IO for redo. Faster disk. Raw file. Direct IO. Dedicated disk. buffer space has too many data on dedicated FLUENTD chunk_limit_size 4MB total_limit_size 512MB flush_interval 30s flush_thread_count 4 retry_timeout 24h logged 404 errors show that there are often reconnect to that AWS ES cluster. just sad that fluentd doesn't have better self recovery mechanisms, and if one index goes down it bring down everything else Tuning the Redo Log Buffer - iDevelopment.info Apr 16, 2001 Troubleshooting SQL Server Transaction Log Related Wait Types Jan 05, 2016
