The service slowly consumes memory. How to localize the problem?

To localize the issue of slow memory consumption by the service, you should:

1. Gather memory usage metrics using profilers (e.g., Valgrind massif, VisualVM, pprof) or built-in monitoring tools.
2. Analyze logs and traces for memory leaks or abnormal object growth.
3. Use heap dump to analyze objects occupying a lot of memory.
4. Check for cycles and caching — objects may not be released due to improper link management.
5. Step-by-step isolate parts of the code to identify the section causing memory growth.

For example, in Java, you can use VisualVM for monitoring and creating heap dumps, then analyze which objects are accumulating.
