Errored WUs [solved]

Hi,
during the last half day, one host experienced Errors with the following WUs:

E202658_ 282_ C.26.C23H15N3.00091949.3.set1d06
E202661_ 374_ C.27.C19H7N3O2S2Se.00400644.4.set1d06
E202660_ 205_ C.26.C24H15NO.00016020.3.set1d06
E202575_ 166_ C.24.C22H18Si2.00015185.4.set1d06

The error messages are:

Application exited with RC = 0xb
[ERROR] Failed to open either source or destination files while copying C.26.C23H15N3.00091949.3.noopt.bp86.sto6g.n.sp/53.0 to C.26.C23H15N3.00091949.3.noopt.bp86.sto6g.n.sp.53.0. Error: 2

It seems that at least one other host experienced the same problem but other hosts were able to perform the job.
The concerned host configuration is:

Boinc 6.10.17 on Ubuntu 10.04, 64 bit
AMD Phenom II x6
Available free disk space for Boinc 10 GB

Cheers,
Yves

Re: Errored WUs

Will be predictable, but for completeness sake, what were the entries in the client message log when these went out?

Re: Errored WUs

Additionally the following WU has been considered as invalid:
E202645_ 564_ C.26.C24H14OS.00327336.4.set1d06

@Sekerob: which message do you mean exactly?

Re: Errored WUs

You've not earned your Guru badge yet ;>)... the messages you can see in BOINC Manager of which a copy is stored in the stdoutdae.txt file. Something will have been logged there too when those tasks bombed.

Since there are no particular error messages in the mentioned file, I was not sure about the file you though about. wink

Re: Errored WUs

In between the list of errored WUs is growing:

E202658_ 282_ C.26.C23H15N3.00091949.3.set1d06
E202661_ 733_ C.27.C19H9N3OS3Si.00312086.2.set1d06
E202661_ 378_ A.27.C19H9N3OS4.263.0.set1d06
E202660_ 668_ C.26.C24H15NO.00100363.1.set1d06
E202658_ 527_ C.27.C20H9N3S4.00368717.4.set1d06

E202575_ 166_ C.24.C22H18Si2.00015185.4.set1d06

But some of them have been successfully computed by other hosts.

Re: Errored WUs

At a loss. The CEP2 logs have wallclock time stamps of the client when something happens and thus surprised your client has nothing for the

"ERROR] Failed to open either source or destination files while copying"

concurrent with these.

Can't think of this being written to any other of the client log files such as stderrdae.txt

Mysterious.

PS: Wonder if WCG has comparative stats of Intel v AMD and their relative error rates.

Re: Errored WUs

I operate currently three AMD-based hosts running Ubuntu 10.04 64. All these hosts crunch regularly CEP2 WUs without any problems. Only the 8 above mentioned WUs are errored.
I share your opinion: that is strange ! ... thinking

Re: Errored WUs

On the same host, 8 more WUs:

E202669_ 091_ C.27.C20H10N2O2S2Si.00445324.3.set1d06
E202670_ 274_ C.24.C20H12SSe2Si.00426670.0.set1d06
E202670_ 291_ C.26.C20H10O3SSeSi.00469894.0.set1d06
E202670_ 010_ C.25.C20H10N2SSe2.00301535.1.set1d06
E202670_ 987_ A.25.C23H18N2.63.4.set1d06
E202669_ 356_ C.27.C20H10N4S3.00529830.0.set1d06
E202669_ 174_ C.27.C21H10N2OS3.00074558.2.set1d06
E202669_ 715_ C.24.C20H12SSe2Si.00177320.4.set1d06

with the same cause, and without any particular error message in stderrdae.txt wink

Question, did the host failed to download some files for CEP2 during the last days?
This problem occurred only on one host.

Re: Errored WUs

Suggest to boot if not done already. Just not getting any ''error'' results at all on me Linux quad [even when running all 4 cores], nor on the W7 duo, where only one at time is allowed.
