Build for ParaView fail because of this error. Could it failed because it is running out of memory? Is this a temporary issue?
Thanks.

build-x86_64
The self-hosted runner lost communication with the server. Verify the machine is running and has a healthy network connection. Anything in your workflow that terminates the runner process, starves it for CPU/Memory, or blocks its network access can cause this error.

You need to reduce the number of parallel jobs or figure out some other way to make it use less memory. ParaView builds already get scheduled on runners with at least 64GB of RAM.
