Re: [HTCondor-users] Jobs getting died on Signal 9

[gagan tiwari <gagan.tiwari@xxxxxxxxxxxxxxxxxx>]

Hi Jason,

          ÂThanks for yourÂemail.ÂÂ

Wanted to share with you couple of detail :-Â

Here is the reason of job crash ( Signal 9 )

condor_history -long 60990.13 | grep -i signal
ExitBySignal = true
ExitReason = "died on signal 9 (Killed)"
ExitSignal = 9
ToE = [ How = "OF_ITS_OWN_ACCORD"; Who = "itself"; When = 1740735423; ExitBySignal = true; HowCode = 0; ExitSignal = 9 ]

We do specify output and error log at the time of submission but didn't find any information in these files.Â

"executable": "$(bin)",
                "arguments": "$(config)",
                "output": "$(outfile)",
                "error": "$(errfile)",
                "log": "jobstatus.log",

Are these not sufficient ? Or do we need to Âspecify "stream_error" in the submit file ?

And here is log from execute node slot on which this job was running :-Â

Can you please help figure out what could be the reason for the job crash with signal 9 with the above detail.

Thanks,

Hi Gagan,

In /var/log/condor on the execution point, the StarterLog for the slot that the job ran on might have some more information on what happened, particularly if it had something to do with condor. If the error is not condor related, one thing you can try when submitting the job, particularly if you have reason to expect it to fail, is to set stream_ouptut and stream_error in your submit file to stream the job's stdout and stderr back to the access point, though you will probably want to limit this to only a couple jobs as it can stress the network and disk of the access point: https://htcondor.readthedocs.io/en/latest/man-pages/condor_submit.html#stream_error

Hi Guys,

           At times , jobs running on exec nodes crashed withÂSignal 9 error. But this is a generic message and we don't know exactly what went wrong with the jobs.ÂÂ

Is thereÂany settingÂin condor whichÂcan be tweaked to provide detailed information about what exactly happened?

Thanks,

Gagan
