MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit List-Id: List-Help: List-Subscribe: List-Post: List-Owner: List-Archive: Precedence: bulk Hi Claudio, We didn't configure any replication to our production server. Which strace are you talking about? We did a keen observation that only at the time 9'th minute of the hour and 39'th minute of the hour the so called archive logs are generated even when nobody is connecting from application(off the business hours). Minimum of 76 files are being produced in these two intervals of a hour. Tried to monitor the DML's but those are the same DML's which were in the past. Any idea?? Thanks in advance. -- Sent from: http://www.postgresql-archive.org/PostgreSQL-performance-f2050081.html
