What is the difference between a direct and indirect leak?

by

The LSan wiki design document states: Another useful feature is being able to distinguish between directly leaked blocks (not reachable from anywhere) and indirectly leaked blocks (reachable from other leaked blocks). Stated another way, indirect leaks are a result of direct leaks. Fixing direct leaks should make the indirect leaks become either fixed or direct … Read more

valgrind memory leak errors when using pthread_create

by

A thread’s resources are not immediately released at termination, unless the thread was created with the detach state attribute set to PTHREAD_CREATE_DETACHED, or if pthread_detach is called for its pthread_t. An undetached thread will remain terminated state until its identifier is passed to pthread_join or pthread_detach. To sum it up, you have three options: create … Read more

How to avoid memory leak with shared_ptr?

by

If you have circular references like this, one object should hold a weak_ptr to the other, not a shared_ptr. From the shared_ptr introduction: Because the implementation uses reference counting, cycles of shared_ptr instances will not be reclaimed. For example, if main() holds a shared_ptr to A, which directly or indirectly holds a shared_ptr back to … Read more

You may be able to do something for your setState as well. Consider trying: setState(() => {…code}) This might also be helpful: When to use React setState callback

Massive memory hemorrhage that causes heap size to go from about 64mb, to 1.5gb in roughly 8 seconds. Issue with garbage collector?

by

Try specifying a garbage collector manually. Concurrent Mark Sweep is a good general purpose one that provides a good balance between low-pause and reasonable throughput. If you are on Java 7 or later Java 6, G1 collector is probably better since it is able to also prevent memory fragmentation. You can check the Java SE … Read more

Why is the memory in GPU still in use after clearing the object?

by

It looks like PyTorch’s caching allocator reserves some fixed amount of memory even if there are no tensors, and this allocation is triggered by the first CUDA memory access (torch.cuda.empty_cache() deletes unused tensor from the cache, but the cache itself still uses some memory). Even with a tiny 1-element tensor, after del and torch.cuda.empty_cache(), GPUtil.showUtilization(all=True) … Read more
