Server closed the connection unexpectedly

[wei]

Hi

I get some problems with the postgre-gis-ha

i  create the cluster with image

--ccp-image=crunchy-postgres-gis-ha   --ccp-image-tag=centos8-13.2-3.0-4.6.2

the cluster runs correctly, but when i get connected to the database; have no opreations for serveral minitus ,i got the following errors

"server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request"

And when i try again(retry the query), it's ok, i get the result !

So, this is a bug to the specific version image?

Thanks

Nope. This is likely due to a connection backend being killed by the Linux OOM.

There is a good blog post on the topic by Joe Conway:
