Memory leak in an infinite service

Sorry for the mistakes I’m making
I need to create a program that runs endlessly, it needs to query records from a postgres database and process this information.

I have a lot of data to process.

The problem is that it is consuming memory and does not release more, I tried everything I read several articles on good practices for database querying and processing with goruntines.

Has anyone ever had a similar problem? or know how I can know which part of the code is not releasing the memory correctly?

Thanks for the help!

If you don’t show us any code, it is impossible to help you.

Can you show us the relevant parts of your code that demonstrates the problem?

pprof with the -memprofile option could be a good start.
Example: go test -memprofile -bench .
