Grammalecte  Help: lock-timeout

The "lock-timeout" setting:

This is the number of seconds that a check-in lock will be held on
the server before the lock expires.  The default is a 60-second delay.
Set this value to zero to disable the check-in lock mechanism.

This value should be set on the server to which users auto-sync
their work.  This setting has no affect on client repositories.  The
check-in lock mechanism is only effective if all users are auto-syncing
to the same server.

Check-in locks are an advisory mechanism designed to help prevent
accidental forks due to a check-in race in installations where many
user are  committing to the same branch and auto-sync is enabled.
As forks are harmless, there is no danger in disabling this mechanism.
However, keeping check-in locks turned on can help prevent unnecessary
confusion.
