Hi,
I have Barman 2.3 set up, backing up a range of PostgreSQL 9.6 servers.
I have my 'backup' command for these servers set to run in the early hours of the morning.
Intermittently this fails, with the following error in the log:
2017-12-13 03:31:00,026 [14519] barman.server ERROR: Check 'check timeout' failed for server 'trapeze'
2017-12-13 03:31:00,033 [14519] barman.server ERROR: Impossible to start the backup. Check the log for more details, or run 'barman check trapeze'
When I run 'barman check trapeze' hours later, everything is fine. I can also run 'barman backup trapeze' and the backup completes successfully.
I'm assuming that there's some sort of timeout occurring, causing an issue, but I'm not sure how to debug the issue further?
I can't think of anything happening during the hours when the cron job runs that could cause this sort of issue, and as I said, the issue is intermittent maybe happening on 10% of occasions.
