We are working to fix the problem preventing the creation of new WUs; once again, the problem is not with BOINC but with another nanoHUB machine on which all the memory is consumed by monitoring these BOINC jobs. We fixed most of the problems with that system but obviously not all of them. Plus, the two of us running this project have been busy teaching a short class for undergrads using nanoHUB for summer research; that ends today, so we will get this fixed ASAP. Thanks for letting us know. Thanks for the update and keep us informed about progress in the project.

Main reason was 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED and some of them were running for over an hour and even longer. Beside those any other invalid tasks were failing due to infamous 196 (0x000000C4) EXIT_DISK_LIMIT_EXCEEDED. Plus there are no more new tasks available again and workunits waiting for assimilation are piling up. Please, give us update on the progress of the project.

If you have aborted a nanoHUB@Home job in your client, what was the reason? In the same analysis we are working to improve the time and disk estimates for nanoHUB tools that produce WUs that fail often. I cancelled some of WUs due to high failure rate caused by EXIT_DISK_LIMIT_EXCEEDED error.

46) Message boards : News : Running again (Message 295) Posted 11 May 2019 by Hal Bregg Post: Right now I have 229 successfully completed tasks with only 26 failed. Majority of tasks were completed on Windows host with small fraction crunched on Linux host.

49) Message boards : News : Request for feedback (Message 287) Posted 27 Apr 2019 by Hal Bregg Post: Almost 300 WUs completed with 28 invalid ones due to some troubles with VirtualBox. All tasks were short. I already enquired about it in this thread https://boinc.nanohub.org/nanoHUB_at_home/forum_thread.php?id=69

51) Questions and Answers : Windows : WU completes with VirtualBox errors (Message 284) Posted 27 Apr 2019 by Hal Bregg Post: One hundred task later and no errors. Memory usage is high so maybe this was casuing problems with VirtualBox.
52) Questions and Answers : Windows : WU completes with VirtualBox errors (Message 283) Posted 26 Apr 2019 by Hal Bregg Post: The PC has AMD Athlon II X2 220 on board. I installed recommended version of VirtualBox (5.2.8) along with Boinc client in version 7.14.2. I switched temporarily to crunching on one core only to see if things get better.
53) Questions and Answers : Windows : WU completes with VirtualBox errors (Message 281) Posted 26 Apr 2019 by Hal Bregg Post: Hello, Just started crunhing for his project on Windows 10 Pro with dual core AMD processor. So I have completed succesfully 97 WU with only 27 failed ones. Failed WUs shows in log this kind of message 2019-04-26 18:03:17 (2776): Error 0x80bb0001 in vbox52::VBOX_VM::create_vm (c:\users\david\documents\boinc_git\boinc\samples\vboxwrapper\vbox_mscom_impl.cpp:643) 2019-04-26 18:03:17 (2776): Error Source : VirtualBoxWrap 2019-04-26 18:03:17 (2776): Error Description: Cannot register the DVD image 'C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso' {c3e0a8b1-76e0-439b-868a-1ad2afa6918e} because a CD/DVD image 'C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso' with UUID {b3cc04de-cd0c-481d-893f-6d957668fcd4} already exists 2019-04-26 18:03:18 (2776): Could not create VM 2019-04-26 18:03:18 (2776): Powering off VM. followed by Hypervisor log. Any advice what could be the problem?
