Failed to allocate a 18874376 byte 
allocation with 18575992 free 
bytes and 17MB until OOM, target 
footprint 268435456, growth limit

}

OutOfMemoryError usually means that you’re doing something wrong, either holding onto objects too long or trying to process too much data at a time. Sometimes, it indicates a problem that’s out of your control, such as a third-party library that caches strings or an application server that doesn’t clean up after deploys. And sometimes, it has nothing to do with objects on the heap.
