1) Message boards : ATLAS application : All new tasks failing after about 5 minutes (Message 45700) Posted 15 Nov 2021 by Cody Post: Thanks for pointing that out. I've 3 boxes and missed that it was misconfigured on that system, now corrected. I've two linux hosts, one windows 10 box, Atlas is failing on all of of them. I've double checked the VB extensions is installed on all systems, and that it matches the version of vbox. Will check to see how that impacts the tasks overnight. C
2) Message boards : ATLAS application : All new tasks failing after about 5 minutes (Message 45696) Posted 14 Nov 2021 by Cody Post: My Atlas tasks are also failing after 10 minutes +- 40 seconds. CMS vbox tasks complete on the same host. System setup Windows 10 recent install, current BOINC verison with virtual box installed. 12 cpu, 32 gb memory, twin 1050ti cards. One example of a failed task is below https://lhcathome.cern.ch/lhcathome/result.php?resultid=332861223 Looking at the log it looks like it fails almost immediately, just 4 seconds after starting, so I'm not sure where that 10 minutes is calculated from.
