Old locks are removed if they are more than one hour old. This means a user may be locked out of accessing a file or a service for up to one hour as a result of a system crash during a critical time period. It is possible to manually remove a lock file if you are positive that no process is actually accessing that file. One reason for the long time period is to allow for the time required to transmit large files over slow links. If you like this site, tell your friends.
