Support Update

  • AGLT2 (BrianL): high load on some worker nodes (ls /tmp hangs) with some ATLAS jobs using 100% of swap. Happening less frequently now
  • Clemson and UERJ (Mat, BrianL): Uncovered an issue in our HTCondor-CE installation doc (separating the job queue log from SPOOL doesn't work). Reverted that documentation for now and we're discussing details with the HTCondor team.
  • GlideinWMS frontends (Edgar): Can't condor_ssh_to_job in OSG jobs, discussing with the HTCondor team. This may be due to singularity and/or shared port configuration.
