Message Type: Information Message

This Message means that the BOINC Client Software has been told by the Project's Scheduling Server to remove a file from the Participant's Computer to free up disk space. The most common cause of this message is a computer that has little free space on the Disk Drive or the Participant has placed strict guidelines for disk usage in their Preference Settings

The solution is to check disk availability and free up additional room by deleting files, or by changing the disk space usage Preference Settings.

Line-By-Line Explanation

• Sending scheduler request to '(url)'

This message indicates that the BOINC Client Software is making the attempt to connect to the Project's Scheduling Server.

• Requesting '(seconds)' seconds of work, returning '(count)' results

Within the Scheduler Request Message we are asking for work to the tune of 57,743 seconds, and also returning no Results to the Project.

• Scheduler request to '(url)' succeeded

This message tells you that the communication session completed without error.

• Message from server: No work sent

But, no work was sent...

• Message from server: (there was work but you don't have enough disk space allocated)

The reason for no work is that you don't have enough free disk space.

• Message from server: Removing file '(file)' to free up disk space

The Scheduling Server is going to attempt to free space by removing a file.

• Got server request to delete file '(file-name)'

The BOINC Daemon is going to remove the file.

• No work from project

However, this still results in no work from the Project.

• Deferring communication with project for "x" hours, "y" minutes, and "z" seconds

Because of the communications failure, we will use Exponential Back-Off to prevent our Host from "flooding" the Server with communication requests. I mean, if it is busy, maybe we should give it a break.
