Since SERVER-32638, global and database locks can be interrupted when an OperationContext is killed and throw a DBException with an Interrupted error code. This includes all AutoGet helpers.
The following places in the sharding code have temporary UninterruptibleLockGuard s to prevent crashing due to inadequate exception handling:
