  == Using the Cooperative File Lock Mechanism ==
  
+ Since Jackrabbit 1.6 an alternative repository locking mechanism is available.
+ 
  Some NFS implementations do not release native locks after a hard reboot. In this case the
workaround is to manually delete all .lock files. Older NFS implementation throw the exception
"No locks available", which means the NFS does not support native file locks.
  
  To solve this problem, Jackrabbit also supports cooperative file locking. This mechanism
is not based on native file locks, but instead uses background threads that periodically update
a sentinel file (lock.properties). The algorithm of cooperative file locking is described
below. To use cooperative file locking, add this to your repository.xml before the </Repository>
tag:
