I do not think thi is a complaint, but just a request for enlightenment. One of my tasks finished overnight, and apparently successfully. Name hadam4h_h0c7_200602_4_920_012115657_0 Workunit 12115657 Validate state Valid Credit 6,897.54 The Credit seems somewhat low, but perhaps this is because it has not yet had its credits all totaled up yet. However it seems to have lots of complaints in the reported stderr file: <core_client_version>7.16.11</core_client_version> <![CDATA[ <stderr_txt> Suspended CPDN Monitor - Suspend request from BOINC...

But the software termination from kill, the Abnormal termination triggered by abort call I do not understand at all. BTW, I am running Red Hat Enterprise Linux 8.4.

I got something similar from my last one, a batch 901. And it went on about 3 times as long as yours. I think that it's just the end code of the task, as it finishes up, having problems. But the task page says that the model finished OK, so I'm not worried. Does anyone think it should be raised with the project? |

I got something similar from my last one, a batch 901. I checked a few others, and they all seem like that. (And all of those completed correctly.) So as I said before, I do not think this is a problem, but something I do not understand. I know CPDN tasks run differently from all the other projects I am on (WCG, rosetta, universe) in that each task is initially spun off by the boinc client. But the task spun off by the boinc client for CPDN then spins off another task (the one that does most of the work) and I imagine the boinc client does not know this. So when the boinc client wants to suspend a task, it may not get the response it is expecting, or at least, not as soon as it expects. But when I look at stderr, it appears (I am not saying this is what happens) that it terminates the process and yet, somehow, the process comes to life and continues. Sometimes more than once. And I do not see how that could be.

My stderr is considerably simpler: <core_client_version>7.16.17</core_client_version> <![CDATA[ <stderr_txt> Suspended CPDN Monitor - Suspend request from BOINC... Suspended CPDN Monitor - Suspend request from BOINC... 13:01:25 (132651): called boinc_finish(0) </stderr_txt> ]]>Computer: Linux Mint 20.2 Result: hadam4h_h15a_201102_4_920_012116704_0 Looks like the extra warnings are actually trying to tell you something significant about how the machine is configured or running - in that case, it's worth keeping them for inspection. |

Would not stderr be the same, either good or bad, if it were a configuration problem?
