Say it like this
- We have a memory leak in production that we need to address immediately
- I found a memory leak in the event handler - it was holding onto references
- The memory leak is causing the application to consume gigabytes of RAM over time
Use it at work
Debugging
- Memory keeps growing until the server crashes. It's a memory leak.
- I think there's a memory leak in the image processor.
Fixing
- Let's take a heap dump to find the memory leak.
- The event listener was never removed. That's the leak.
Status
- We fixed the memory leak. Memory is flat now.
- The pods restart every day because of a memory leak.

More about memory leak
Real examples(3)
- in a standup
"Yesterday we identified a memory leak in the user session manager that was preventing the garbage collector from cleaning up old sessions."
- in a code review
"This callback function creates a closure that captures the entire context object, which could cause a memory leak if not properly cleaned up on unmount."
- in a team meeting
"The DevOps team reported that the API server is consuming 15 GB more memory each week, so we suspect a significant memory leak somewhere in the codebase."
More mistakes(2)
Handle with care. Non-native speakers sometimes confuse memory leaks with other memory issues like stack overflow or buffer overflows. A memory leak specifically means allocated memory that is no longer accessible but not freed.
- ✕We need to memory leak the code before deployment.✓We need to fix the memory leak before deployment.
Memory leak is a noun describing a problem, not a verb. You fix or patch a memory leak, you do not perform the action of memory leaking
- ✕This memory leak will be memory leaking for hours.✓This memory leak will persist for hours if we don't address it.
Memory leak is not used as a verb in standard technical English
Other forms(3)

Questions(5)
- What does memory leak mean in software engineering?
- A memory leak occurs when a program allocates memory but fails to release it back to the operating system when it is no longer needed. This causes the program to consume increasingly more memory over time, eventually degrading performance or causing crashes. Unlike temporary storage issues, memory leaks are permanent losses of accessible memory within a running process.
- How do you use memory leak in a sentence at work?
- You typically use memory leak as a noun in technical conversations. Examples: We discovered a memory leak in the authentication service, The memory leak is causing the application to crash, We need to fix this memory leak before production, or The profiler revealed multiple memory leaks in the codebase. You can also use it with adjectives like serious, critical, or minor to describe severity.
- Is memory leak formal or informal?
- Memory leak is neutral in formality and is used in both formal technical documentation and casual team conversations. It is a standard technical term understood by all developers and is appropriate for code reviews, meetings, documentation, and interviews.
- What languages are most susceptible to memory leaks?
- Languages with manual memory management like C and C++ are most susceptible because the programmer must explicitly allocate and deallocate memory. However, memory leaks can occur in any language, including Java, Python, and JavaScript, typically through circular references or event listeners that are not properly cleaned up.
- How do you detect and fix a memory leak?
- You detect memory leaks using profiling tools like Valgrind, AddressSanitizer, Java Flight Recorder, or browser developer tools. To fix them, you must identify where memory is allocated but not released, then ensure proper deallocation using techniques like freeing pointers in C, using finally blocks, or removing event listeners and circular references.
