    4040 --purge_stale X::
    4141        remove work items from the shared memory segment that have been there for longer than x minutes but haven't been assigned
    42  -appids N1, N2, ... ::
     42 --appids N1, N2, ... ::
    4343   Get work only for the given apps.
    4444   Useful if your project uses both locality and job-cache scheduling.
     
    6060 -d N:: debug level N (1 .. 4 = most verbose)
    6161 --mod n i:: process only workunits with (id mod n) == i

     63The transitioner works asynchronously from work generators and schedulers,
     64and in high-load situations it can fall behind
     65(i.e. a large queue of workunits waiting to be processed can build up).
     66The transitioner backlog is shown in the server status page.
     67If the backlog becomes large (> 1 hour) you can do the following:
     68
     69 * stop the project
     70 * run '''sched/transitioner_catchup.php'''
     71 * start the project
