Craig Condit updated YUNIKORN-3000:
-----------------------------------
Description: As of Go 1.19, Go supports reading a {{GOMEMLIMIT}}
environment variable to limit the amount of RAM the process will use before
garbage collecting. This is a soft limit, but helps constrain resource usage
and can help avoid being OOMKilled by Kubernetes. Since we set our existing
memory request to 1 GiB, and limit to 2 GiB, I propose setting the default
{{GOMEMLIMIT}} value to 1.5 GiB. This allows for non-GC overhead plus transient
spikes, and should keep us well under the threshold for being OOMKilled. We
should also allow overriding {{GOGC}} as well. (was: As of Go 1.19, Go
