Our system routinely crashes with out-of-memory errors every few days. A colleague suggested applying a temporary patch by augmenting the values. Does increasing heap memory fix memory leak issues over time, or are we just delaying an inevitable production crash?

Increasing the boundaries will absolutely not fix a genuine memory leak. A leak happens because your application code maintains active, unintended references to objects that should be discarded, preventing the automated cleanup engine from reclaiming that space. By expanding your configuration limits, you are simply purchasing a slightly longer runway before the system fills up completely and crashes again. The application will continue to consume resources at a steady rate until it hits the new ceiling, meaning you have only prolonged the time between restarts while making eventual troubleshooting harder.
Have you tried utilizing runtime profilers or taking automated heap dumps right before the system drops? Pinpointing the specific object classes that multiply endlessly is the only true way to address structural leaks.
It acts as a temporary band-aid solution. It buys your engineering team a little extra time to find the rogue code references causing the inflation.
Thanks for the honesty, Diane. We will use the expanded allocation space strictly as an emergency buffer for this week while our core development sprint prioritizes refactoring the connection classes to drop active references properly.
Arthur, I followed your advice and initiated a heap dump capture using Eclipse Memory Analyzer. It quickly showed that an unclosed telemetry connection pool was retaining millions of session state tracking objects, confirming that adjusting our heap configurations would have never solved our core issue.
