Ivan, does the above mean that this is your last day or that you are hoping for a new contract in the post ?

Yes. I've now had a .pdf by e-mail, but am still waiting for the paper copy to sign. So barring accidents, you've probably got me for another year...

Congratulations, hope the print isn't too small.

Just the usual (but at least it's not in Comic Sans) -- and thankfully no mention of my passing National Retirement Age later this year (but that discrimination is outlawed here now :-).

The only host I could find with that many fails had quite a few successful jobs too. The one failure I looked at was an exception of some kind after 180 or so events -- it may be running close to the system memory limit or similar.

There are two individual IP addresses, that produce a lot of fails.
Mostly exit code 134.

Memory problems, by the look of it; access exceptions, etc. Both from vLHC project. PMs sent; one is in Japan so may not respond immediately due to time-zone differences.

Some sort of glitch; one in the afternoon then 4 in quick succession in the night. -- Ah, same user I tried to contact yesterday; will send an e-mail...

There is , again, an increase in error rate.
It is not that dramatic but , again, caused mainly by one or two IP addresses.

If there was a system in place to eliminate the worst two or three hosts(IPaddresses), the error rate could be improved by 50% or more.

Are they WMAgent jobs? I don't see many failures in my CRAB3 jobs. There's one user failing with WMAgent because of an apparently misconfigured firewall but I don't think anyone's managed to get a response from him yet.

I know it's on Laurence's to-do list, but so are 101 other things. :-/

It seems to have stabilized.
I always get a bit nervous , if there are 5 or more fails from the same IP in a short period of time.

I think, 0.5% error rate is about normal.Up to about 1%, there are usually some dodgy hosts and anything going over 1.5% indcates server issues.

I guess, as you have an unlimited supply of jobs and a failed job gets reassigned, the only real issue is wasted computing time.

Maybe, i just want the error stats to look as good as possible.

EDIT:
Are they WMAgent jobs?


I don't think so.

There's a ticket out at the moment (or at least was yesterday) that WMAgent jobs weren't being reported properly. I can see 98 WMAGent Condor jobs running at RAL at present (alongside 102 of my CRAB jobs), and there are 10,000 in the queue.

Thanks, Ivan.
Even if there is (was) a problem, it would not cause individual IP addresses to cause more fails, would it?

No, but we don't seem to be getting the full picture of what is running.
