I posted minirosetta version 1.29 and rosetta_beta 5.97 on ralph which both include a fix for this bad bug that stalls clients. The problem was a possible infinite loop in the boinc api when an access violation caused by our t405 job was caught after the job completed. Hopefully the tests running on ralph will confirm the fix. Thanks David! I really need to get back to Rosetta. Let's hope this works. Tim  |

If it was an infinite loop, surely the task would still be using 100% of it's core, just doing nothing? It looked more like some asynch call had been fired off and the task was sitting idle waiting for a completion status that never appeared. Also, mine were sticking part way through the job, not at the end. Wave upon wave of demented avengers march cheerfully out of obscurity into the dream. |

Here is David Anderson's take on the issue: "Our guess is that something called from exit() (either an atexit() function or something internal to the C library) was causing a signal, and the signal handler (boinc_catch_signal()) called exit() which made the same thing happen, infinitely. I changed the signal handler to call _exit() instead of exit()." That change prevented the hanging in our local tests. I don't know what was happening with your particular job that was hanging mid run. Are you absolutely sure it was hung up? |

24 hours of crunching time lost to a validate error: t405__CASP8_JUMPAB_TYPE2_RES81to192_SAVE_ALL_OUT_BARCODE__3785_36095_0 I hate it when that happens... Rosie, Rosie, she's our gal, If she can't do it, no one shall! |

Are you absolutely sure it was hung up? I am absolutely 100% certain they, (note plural), were stuck! I am not stupid, if I see my quad CPU temperature bobbling around 35C I KNOW something is odd. When I look at BM and see that I have 4 tasks "Running", and yet, see from Process Manager that I am running 25% or 50% Windows Idle Process, (depended on which machine I was looking at), then something is screwed. So I suspend each project in turn until I see which is wasting the time, and was suprised to see it was Rosetta. As soon as I suspended Rosetta, the other projects tasks started and filled the machines to 100%. Release the suspended tasks and they start again, they sit there with wall time and completion % fixed. If you read the thread, you will find others with similar stories. Suggesting we are "mistaken" is sticking your head in the sand, there is an issue here. It also irritates. I don't suspend Rosetta lightly, but it was clear to me that there was a problem.

Are you absolutely sure it was hung up? Yes, before I suspended Rosetta, none of my tasks of version 5.96 went to completion at 100%. All were hung prior to 100%. Task manager in windows showed exactly 50% system idle process. One core was always idle. |

Are you absolutely sure it was hung up? I was just trying to double check. I hope this is a related problem that will be fixed with the api change. Bottom line is that the t405 task has uncovered a bug in rosetta++ that has to be fixed for that particular protocol which is important for some casp targets. Sorry, I wasn't assuming you were wrong in your diagnosis, just double checking to make sure. |

does anyone know if these tasks will be aborted after 4 restarts? I've got quite a few remotes that I don't have much contact with and assume at least some of these will be hit by the bug... |

Looked at my multi-core AMD machine (64-bit Linux client) and saw that four cores were idle... I'm experiencing the same issue where the tasks will get to 100% then idle. (Ubuntu 8.04 64 bit on a Intel Q6600). |

https://boinc.bakerlab.org/rosetta/result.php?resultid=171780274 please post for the team, why you aborted this task. this will help them solve whatever problem you and others might be having. |

Actually I believe it would be 5 restarts. So when any specific task has run long enough that it records it's initial information, and hasn't made any progress (i.e. saved a checkpoint) since the last restart, if this occurs 5 times, the task will be ended.

I'm experiencing the same issue where the tasks will get to 100% then idle. (Ubuntu 8.04 64 bit on a Intel Q6600). Just a "me too", using 32 bit Ubuntu 7.10 and a dual core Athlon. I haven't checked today to see if crunching had resumed. It would be nice to get the answers to these questions: 1. Is there a known issue with crunching stopping after WUs reach 100%? 2. Are we supposed to "wait it out" or take some action? Stephen |

I've noticed some "watchdog" processes in ubuntu that have RT priority. Could these be pushing boinc into the background? |

I'm experiencing the same issue where the tasks will get to 100% then idle. (Ubuntu 8.04 64 bit on a Intel Q6600). There is a known problem that is most prevalent with t405 tasks (which have been canceled since) that can cause the client to stall when the task is complete. If you have a task at 100% and your cpu(s) are idle please click the update button on the boinc manager for the project while connected online and if the task persists, abort it. We are testing a boinc api fix for this on ralph. |

It is a shame that the t405 cancellation wasn't mentioned when it was done, I could have resumed Rosetta then instead of now! The news flow is certainly a bit stagnant, I appreciate CASP is a busy time, but a couple of lines on the news column on the front page would not take long.
