Message Type: Warning Message

This Message means that the BOINC Client Software was unable to locate the "Master Page" when using the Project's Master URL because of a network problem. There are many causes for this error, to include:

• Complete networking failure
• The Project's Web Server is Off-Line
• The Internet Service Provider is Off-Line

More details on Error Codes can give you a better idea of why the failure occurred.

[edit] Version Information

[edit] Message Added

New in BOINC Client Software Version: 4.46

[edit] Alternate Message Formats

• Couldn't read master page for '(project identifier)': error '(error-code)'

Obsolete/Changed in Version: 4.46

Because the message is entered into the log with the Project Name the Project's Master URL is not required.

[edit] Example Log(s)

[edit] Master File Fetch Failed

In this example the Project's Web Server is the Server that is Off-Line at the moment. This means that the exact messages are slightly different. The end result is the same as you cannot perform the upload of the Result Data File.

Line-By-Line Explanation

• Can't resolve hostname '(host-name)' (valid name, no data record of requested type)

This message tells you that the normal mechanisms that translate human usable addresses (like a URL into the actual IP Addresses that are used by the computers.

• Couldn't read master page for '(project identifier)': error '(error-code)'

This line tells you that the BOINC Client Software was unable to contact the Climateprediction.net's Web Server.

• Master file fetch failed

This message is telling you that the Web Page that is at the Project's Master URL was not available.

• Backing off "x" hours "y" minutes "z" seconds on transfer of file '(file)'

The BOINC Client Software is going to wait for a short interval of time, calculated using the Exponential Back-Off. And in this case, the time is very short. Be advised that it goes up pretty fast!

[edit] Can't Resolve Hostname - Host Not Found

Note:

In this log example, I tried to attach to a Project with a "bogus" URL, just to make this set of messages ... but this is still the error you would get regardless of the reason that the URL is bad.

Line-By-Line Explanation

• Can't resolve hostname ['(host-name)'] host name not found

The "host-name" used is in error, usually caused by incorrect typing or copying of the URL when "Attaching" the BOINC Client Software to a BOINC Powered Project.

• Couldn't read master page for '(project identifier)': error '(error-code)'

Because the Project's Master URL was wrong, the Project's Master Page could not be read.

• BOINC couldn't get main page for '(url)'

Please check the URL and try again.

The BOINC Client Software is offering a hint as to the problem.

• Resetting project
• Detaching from project

And, because of that, we have to "Detach" From The Project, which includes a Project "Reset".

[edit] Scheduler Request Failed HTTP Insert (-113)

This error means of course that the BOINC Client Software was unable to resove the Project's Host name (convert the text into an IP Address).

Line-By-Line Explanation

• Scheduler request to '(url)' succeeded

And in this case we had success! Unfortunately ...

• No work from project

No work available, so lets wait ...

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

Now, we will wait for some interval of time set by the Exponential Back-Off Mechanism, only to have the wheels start to come off the wagon ...

• Sending request to scheduler: '(url)'

Now we are again asking for more work by submitting a request to the Scheduler.

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

And asking for 8,640 seconds worth of work ...

• Can't resolve hostname '(host-name)' host name not found

But now the Server cannot be found!

• Scheduler request failed HTTP insert: '(error-code)'

And this causes an error in the creation of the Scheduler Request Message...

• Scheduler request initialization to '(url)' failed, error '(error-code)'

With our previous error, we did not complete the initialization of the communication session with the Scheduler.

• Init_op_project failed, error '(error-code)'

And we exit the communication process; to then wait ...

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

Now, we will wait for some interval of time set by the Exponential Back-Off Mechanism.

• Can't resolve hostname '(host-name)' host name not found

And we still cannot locate the Server. But now we have a new problem ...

• Couldn't read master page for '(project identifier)': error '(error-code)'

With the Server off-line, the Master Page can't be found ...

• Master file fetch failed

Causing a "fetch" failure ...

Later ...

• Scheduler request to '(url)' succeeded

And in this case we had success! Unfortunately ...

• No work from project

No work available, so we will have to wait again ...
