Our company does soak/longevity testing. Typically we'll take a build and let it run for a few weeks during development to find memory leaks. Then the final release enters our longevity lab where we put it under some amount of load and let it run until the device or VM is retired. It won't necessarily find the bug before final release, we could either recall that version or submit an immediate maintenance version that fixes the issue once discovered. Software will always have bugs, we've chosen to approach it as "find the bugs before the customer" rather than "stomp out every possible bug". Because you are right, we don't get 2 months to pause and fix bugs, and also customers will always do some crazy configuration or workload you didn't have a test case for.
