Yes, it's a potential problem. The server will clear the lock eventually after one of the applications has been shut down forcibly. The best solutions is not to use SET REPROC TO -1. It's generally a bad idea unless you know that this situation will never happen. It's better to try your lock for some amount of time, then unlock everything and inform the user that the operation couldn't be completed.
