Message Type: Error Message
This Message means that the BOINC Client Software was attempting to communicate to the Project's Scheduling Server but encountered an error as it was creating the Scheduler Request Message for sending to the Scheduler.
This error occurs during the initial stages of the communication session between the Participant's Computer and the Project's Scheduling Server.
[edit] Version Information
- None.

[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
- And in this case we had success! Unfortunately ...
- No work available, so lets wait ...
- 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 ...
- Now we are again asking for more work by submitting a request to the Scheduler.
- And asking for 8,640 seconds worth of work ...
- But now the Server cannot be found!
- 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.
- And we exit the communication process; to then wait ...
- Now, we will wait for some interval of time set by the Exponential Back-Off Mechanism.
- And we still cannot locate the Server. But now we have a new problem ...
- With the Server off-line, the Master Page can't be found ...
- Causing a "fetch" failure ...
- Later ...
- And in this case we had success! Unfortunately ...
- No work available, so we will have to wait again ...

This sequence of messages occurred because the Participant's Computer did not have the proper permissions set on the BOINC Directory and the sub-directories.

Line-By-Line Explanation
- We were suspended for any number of reasons, but now we can go back to work.
- Because we have nothing going on, reschedule the CPUs.
- Scheduler request initialization to '(url)' failed, error '(error-code)'
- Unable to write to a file or directory we cannot make a Scheduler Request Message. If we cannot make the message file to send, then we can't initialize the communication session.
- So we use the Exponential Back-Off Mechanism to wait a bit.
- Meanwhile lets try another Project.
- Scheduler request initialization to '(url)' failed, error '(error-code)'
- Unable to write to a file or directory we cannot make a Scheduler Request Message. If we cannot make the message file to send, then we can't initialize the communication session.
- Two strikes! We cannot initialize and start processing Results for a Project because we do not have any, and we cannot get any because we cannot make a Scheduler Request Message.
- So we use the Exponential Back-Off Mechanism to wait a bit.
- Because we did not have a successful start of work on any Project, we have to schedule the CPUs which means we have to get work ...
- From this point forward, the cycle of messages will repeat forever. The BOINC Client Software must have the ability to read and write files within the BOINC Directory and all of the sub-directories.
