                                            25 minutes, and 37 seconds

Line-By-Line Explanation

The Participant's Computer is asking for more work by submitting a request to the Scheduler.
The Scheduler Request succeeded.
  • Message from server: No work sent
But, no work was sent...
Because: The Host has already download the maximum allowed number of Work Units.
Results in no work from the Project.
Now, we will wait for some interval of time set by the Exponential Back-Off Mechanism.

Line-By-Line Explanation

The Participant's Computer is asking for more work by submitting a request to the Scheduler.
The Scheduler Request succeeded.
  • Message from server: No work sent
But, no work was sent...
Because: The Host is not the same as the other Hosts that the available work has already been issued to and is being processed by those Hosts. This is a feature to ensure better matching of the Results and is called Homogeneous Redundancy.
Results in no work from the Project.
Now, we will wait for some interval of time set by the Exponential Back-Off Mechanism.

[edit] Message From Server: (There Was Work But You Don't Have Enough Disk Space Allocated)

                                                 don't have enough disk space allocated)
(3) 2005-05-12 09:55:26 [ProteinPredictorAtHome] Message from server: No disk space 
                                                 (you must free 100.0 MB before BOINC gets space).  
                                                 Review preferences for maximum disk space used.
(4) 2005-05-12 09:55:26 [ProteinPredictorAtHome] No work from project

Line-By-Line Explanation

  1. Message from server: No work sent
    A Scheduler Request Message was sent to obtain more work, but the Scheduler did not return any work.
  2. Message from server: (there was work but you don't have enough disk space allocated)
    Because there was not enough space left on disk drive on the Participant's Computer. Without additional space there is no room for the additional work.
  3. Message from server: No disk space (you must free '(number)' MB before BOINC gets space). Review preferences for maximum disk space used.
    You must free up this much space to obtain more work from the Project.
  4. No work from project
    So the end result of this exchange of Messages is no new work.
