Hello

at site RO-14-ITIM, we have a very strange problem.

A ticket was raised with the following:

"Hi, The new ticket (Pilots disappearing from local batch system at ITIM) has been created by "*Timo Wilken*". Group: NGIs › NGI_RO Owner: - State: in progress Information: Hi, Pilots seem to be lost by the local batch system at ITIM. >50% of pilots fail: https://apfmon.lancs.ac.uk/CERN_central_A:RO-14-ITIM-arcn-node?state=fault Example log: https://aipanda156.cern.ch/condor_logs_2/25-03-12_13/grid.15478691.1.log Error message: "ARC job failed: LRMS error: (-1) Job missing from SLURM" Cheers,

Timo"

The problem is I can not find any of the jobs that are failing on the site:

for example:

the last job:

https://aipanda023.cern.ch/condor_logs_2/25-03-14_09/grid.19602200.0.log

with stdlog:

I have on my site this kind of error

The ENDPOINT affected is arcn-node.itim-cj.ro (ARC-CE)It became Critical*at*2025-03-14T09:16:44Z due to *METRIC*org.nordugrid.ARC-CE-sw-gcc

*Summary:*Script exited with code 127. Could not match GCC version. See /etc/arc/nagios/20-dist.ini for debugging hints. *Message:*''

which is going to be ok in the messag, one minute later

The ENDPOINT affected is arcn-node.itim-cj.ro (ARC-CE) It became Ok *at* 2025-03-14T09:17:53Z due to *METRIC* org.nordugrid.ARC-CE-sw-gcc *Summary: *Found GCC version 11.5.0. *Message: *''

Can you please advice where to look for any clue in solving this mystery?

Thank you Felix
