Hello,
I have two servers connected to the same switch running postgres 11.5
I am trying to replicate one of those servers after a planned work on the master, so the replica has been lost. It has always worked but now I get this :
pg_basebackup: could not receive data from WAL stream: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
I don't really understand what the issue is.
I had this issue last week as well in another DC and I had to reboot the slave to make it working (not sure why it helped)
Do you know what can cause this?
Thank you,
Nicola
