Unrecoverable error for result '(result)' ( - exit code -5 (0xffffffb))

[edit] General
Message Type: Error Message
This message means that the BOINC Client Software has detected a failure of the Science Application which has occurred because of an internal error (it "crashed"). These errors may be the result of a hardware error, but are more likely because of a problem with the Science Application software and the Work Unit that it is trying to process. These errors should be reported to the Project so that they can try to find the problem in the software.
[edit] Climateprediction.net
While we know about these crashes in the Climateprediction.net's Science Application occur in both the Classic and the Versions Powered by BOINC, they tend to be machine specific. Occasional crashes may indeed relate to the particular Work Unit, but experienced Participants know they are comparatively rare.
Hardware is one of the more common causes of failure in Climateprediction.net because it stresses machines far more than most things, and doubters have often come back later after having tracked down a fault. The rest of these causes are elusive, but the occasional success in finding the cause, as with Anti-Virus software or driver conflicts, show that it is well worth looking for these other causes.
[edit] Diagnostics
You may want to consider trying the following procedures to see if they isolate any problems with your computer. Remember, the BOINC Client Software and the Science Applications we run put tremendous strains on the computers. Some machines will have more problems than others. Using "aggressive" over-clocking can increase the incidence of problems.
[edit] Version Information
- None.

Line-By-Line Explanation
- And now it has restarted processing. There is little difference between "Resuming" and "Restarting", "Resuming" occurs if the Result's information is still resident in memory and the "Restarting" indicates a reload of the in-progress information.
- Unrecoverable error for result '(result)' ( - exit code -5 (0xffffffb))
- The Science Application has "crashed" and stopped processing the Result/Work Unit.
- Because of the "crash" the current Result has been halted. This Result, when the Reporting Process is complete will be recorded with an Outcome of "Client Error".
[edit] Permanently Failed Upload of File
This error means that the BOINC Client Software when it uploaded the Result Data File to the Project's Data Server the Signature did not validate. Because of this the file is considered corrupted and a security risk.
Because of the security implications, the file will not be accepted and it is rejected and immediately deleted from the Data Server.
One of the minor interesting items in this message display is the fact that you can see that two upload threads are run and because they fail at different rates, the messages become interleaved. In a specific example, fine #1 and #2 are started, #1 fails and #3 is started before #2 fails. Hey, sometimes I get bored with this stuff and wonder if anyone reads any of it at all.

Line-By-Line Explanation
- We restart a Result that has already been partially processed.
- Unrecoverable error for result '(result)' ( - exit code -5 (0xffffffb))
- The Science Application has "crashed" and stopped processing the Result/Work Unit.
- Because the Science Application ended processing (it "crashed"), we need to start up another Result.
- Because of the "crash" the current Result has been halted. This Result, when the Reporting Process is complete will be recorded with an Outcome of "Client Error".
- We start to upload two of the 5 Result Data Files.
- We will continue to attempt to upload the other Result Data Files in turn, each will fail upload with the following sequence of messages ...
- The Signature of the Result Data File is incorrect.
- Because of the invalid signature, this Result Data File cannot be accepted by the Data Server.
- The Data Server rejected the file because of the invalid Signature and we cannot assign a different signature, so abandon the attempt to upload the file.
