During shutdown, some database checkpointing and cleaning threads may remain active even after the default time period on systems with very large or very busy database backends. If checkpointing or cleaning is aborted prematurely, it could possible lead to significantly longer startup times for the Directory Server. The Directory Server provides an option for administrators to set the maximum time a shutdown process should take. When a shutdown process is initiated, the server begins stopping all of its internal components and waits up to 5 minutes for all threads to complete before exiting.
Administrators can use the dsconfig tool to increase the maximum shutdown time to allow database operations to complete.
