>If you are marginal on space available, the slightest delay can cause the replication slot to run out of space. >So increase your space. How can I judge myself that marginal space is left available. But the fact is I do still have 50 GB of additional disk space available(on the mount point where the postgres 10.4 data directory runs) when I issued "df -kh" . So I need to have a valid justification in order to ask the systems team for space getting added. But still I'm unable to find any reason from our conversation. But the point I wonder is the snaps are getting automatically deleted and the error stops producing for a period of time. Looking forward to touch the pain area(if at all the server feels). Looking forward to hear from you. Thanks in Advance. Regards, Pavan -- Sent from: http://www.postgresql-archive.org/PostgreSQL-admin-f2076596.html
