How does the MID Server process lock the log file upon startup?

The MID Server processes the lock on the log file upon startup to ensure that only one instance can access it at a time. This is crucial for maintaining the integrity of the logging process. When multiple instances access the same log file simultaneously, it can lead to race conditions, corrupted data, and inaccuracies in logging information. By locking the log file, the MID Server guarantees that once it has started, it will manage its logging operations without interference from other instances, thus ensuring accurate and reliable logging. This approach helps maintain a clear and organized log history that is essential for troubleshooting and auditing purposes in a ServiceNow environment.
