LockTimeout value about nhibernate.caches.redis HOT 1 OPEN

The LockTimeout is how long NHibernate should hold onto the lock. By default, it's a large number of seconds to account for any problems. It's the upper bound of your transaction duration. It's definitely safe to make it 1-2 seconds. However, you need to ensure everything else occurs within the lock timeout as well (e.g. what's your DB timeout?). A possible worst case scenario is:

1. A lock is taken.
2. Some sort stall during your request causing the lock to timeout (e.g. DB connection, network latency etc)
3. A concurrent transaction takes a lock (because the other lock timed out).
4. The original transaction tries to free the lock, but it doesn't own it anymore (thus triggering the RedisCacheProviderOptions.OnUnlockFailed... which may throw an exception depending on how you have it configured).

The default is very high to simply account for these scenarios, but it could be any value depending on your application's requirements.
