Created attachment 468196 [details] oom error We allocate a shared memory by this function, but after refreshing the page multiple times, we will get the memory failed without any error in console. After adding a try...catch, we can catch an error OutOfMemory. It seems that the memory is not released after refreshing the page, causing the new memory to fail to initialize. function AllocateWasmSharedMemory(init, max) { return new WebAssembly.Memory({ initial: init, maximum: max, shared: true, }); }
