LHCb Simulation "errors"

Posted: Tue Jun 27, 2017 9:23 pm

Hi all

So, after the Sprint, I've been finishing off some tasks that were downloaded.

All of the SixTrack tasks were completed and most are in a validation queue.

However, I also had some LHCb and CMS tasks, both of which use VirtualBox.

I've been monitoring the LHC website to ensure my cache was slowly going down and for the last few hours it wasn't - the LHCb and CMS tasks take a while, so I logged onto the PC and all I saw were errors...looks like the PC was spinning it's wheels for the last day or so, as there are lots of tasks that errored, after quite a bit of crunching time.

So, I took a look at a STDERR report and this is what I saw:
Stderr output
<core_client_version>7.6.33</core_client_version>
