From this post you may find that you need a more recent version of libseccomp than the one that comes with Ubuntu 14.04. If you can, move to 16.04. That one works.

I have the same problem. First reported with the dev tasks here.
It occurs from both Windows and Linux hosts - all of them and every task fails. The Linux hosts have CVMFS installed. If run from the command line (the local) CVMFS works, so the system here isn't blocking access, but it seems not from the VM. Fails both using the local proxy and direct. VBox is v5.2.x. Haven't (yet) tried different VBox versions.

IIRC runc requires at least libseccomp.so.2.3.1 which might not be present on older linux systems.

OK that's helpful, thanks, and for the instructions, too. In the meantime I had found and installed v2.2.3-2 (from trusty backports) which didn't help.

You may try to copy libseccomp.so.2.3.1 or a more recent libseccomp from a newer linux

I've got the .deb archive for 2.4.1 (which appears to be available as a security update for 16.04) but can't get a usable library file out of it. It's 41bytes and shows up as a "broken link" I've clearly done something wrong somewhere.
It looks like moving to OS version 16.04 might be needed but that means much downloading.... don't want that at the moment., so the hunt goes on.

Any ideas welcome
9) Message boards : News : new exes for SixTrack 5.02.05 (Message 39042)
Posted 4 Jun 2019 by m

It should be noted that all Win exes are distributed without targeting specific kernel versions - hence, XP hosts may receive tasks with regular Windows exes immediately failing, but the BOINC server should quickly learn that the XP-compatible exe is the appropriate one.

It doesn't seem to be learning very quickly. At the time of writing one host has received 17 "regular" tasks, which failed and 7 "XP" ones which are OK. The details are here
If it doesn't improve I'll try an app_info file to make sure it uses the correct exe.

Posted 7 May 2019 by m

Microsoft has stopped support to XP 5 years ago.

Not quite, at least for 32 bit systems; this is (part of) the last XP update..

2019-04 Update for POSReady 2009 for x86-based Systems (KB4487990), Windows XP ... Update for WES09 and POSReady 2009 (KB4468323), Windows XP ...as far as I'm aware, this really is the end of free MS support.

and there's an (unofficial) SP4. However there is clearly a limit on the effort that can be justified for this.

[edit] Updating from XP often involved scrapping a lot of still serviceable hardware which must have quite an environmental cost, If this can be reduced without too much trouble , it must be good [/edit]

Where do you get the "events done 758000 attemps 49 success 30 failure 1 lost 18" data?

You can get info like this...

From one of the MC pages, such as the status page or the one that shows the results for your user id, you may already have a shortcut to this,

click "Control".
Then, on the highlighted line, click the entry in the "coverage" column.
The "Runs summary" lets you pick the results category you want.. I don't know why results are "Masked". maybe it's not as simple as it looks but the rest seem self explanatory. Try "Unsuccessful". I think that all these are run on BOINC, maybe not all by us volunteers. I'm sure someone from the project will explain further.

15) Message boards : LHCb Application : New version v1.05 (Message 36998)
Posted 10 Oct 2018 by m
Many thanks for the comments.

... CPU usage of lhc VBox WUs should be planned using a calculation factor of 1.3.
Thus a 2 core CPU like the ones you use to run LHCb would be able to run a 1-core setup.

They will, it's just that they used (still do sometimes) to run 2 core jobs without obvious problems.
To test if your hosts are able to deal with a 2-core setup you may monitor your host's "load average" using top or htop. The values should not be much higher than the number of CPU cores. Otherwise it indicates a too busy system.

I'm sure you're right.
There are four hosts here that normally run LHCb (along with others) - stayed up late to last night to check...
1 Running LHCb (2 core) and TNGrid jobs, load average 1.2 - 1.5 The LHCb was running OK, although, as others have commented, the CPU time looks a bit low.
2. Running LHCb(single core) and TNGrid. Load average 1.2 - 1.3
3 Running two TNGrid, load average 2.01 - 2.1
4. Running TNGrid and Theory (single core). Load average 2.01
If your system is too busy you may consider to run your VBox tasks as a 1-core setup.

I don't know it these loads are too high, but they're running single core now so I'll see what happens.
I expect that the loads depend on the exact nature of the job being processed at the time and the hosts are just too close to their limit. It will be a few days before I know.

Another one,,https://lhcathome.cern.ch/lhcathome/result.php?resultid=205073544

In pinciple this doesn't seem to be a new problem; all the current VM projects suffer.- it's just worse.
Tasks seem to fail on restart if the wrapper doesn't "see" that a job been completed..
Previously this information appeared to be "saved" over the shutdown
so a failure only occurred if no task had been completed before the shutdown.(I've got lots of these...)
This "saving" no longer happens, or it's hidden inside the container, so tasks fail.

It's probably more complicated than this, but this is how it seems to behave here.

the VM still sometimes fails to use the local squid.

Do you still have some VMs with errors?

Yes, in total I have details of three tasks:-
In all cases the proxy was reported as detected, but the VM was not reported as set up to use it.
Entries in the access log are taken to show that the proxy was (or wasn't) actually used.
https://lhcathome.cern.ch/lhcathome/result.php?resultid=200124140 ( Proxy used).
https://lhcathome.cern.ch/lhcathome/result.php?resultid=200145344 ( Proxy not used)
https://lhcathome.cern.ch/lhcathome/result.php?resultid=200221912 ( Proxy used)

The last two are the same host.

The inconsistency is puzzling. I'll have to wait for some more. If anyone else sees these failures it would be interesting to see their results. Hopefully I haven't misread something somewhere...
