Hi, Thanks for the input. User is not near quota and can just rerun the job and it works so its not a repeatable operation which makes it harder to diagnose if the software is doing something particular strange (that is why we only see it in particular software) which we could workaround in the meantime some-how.
Hopefully with the information we do obtain when it freezes it is pointing us to some possible solution.

This was landed to work around quota hitting a similar hang with quota: https://jira.whamcloud.com/browse/LU-18691 LU-19180 is in progress to resolve the interop: https://jira.whamcloud.com/browse/LU-19180 > Thanks. > > > Tom > > -- > > *Thomas Green* > _AI Supercomputing Infrastructure Specialist_ > > University of Bristol, 1 Cathedral Square, Trinity Street, College > Green, Bristol > BS1 5DD, UK > > Tel:+441174550298 <tel:+441174550298> > BriCS webpage: http://bristol.ac.uk/supercomputing <https:// > urldefense.com/v3/__http://bristol.ac.uk/supercomputing__;!!NpxR! > htdOeS8P8g4PHzBcH65G_4DY52dNiVAnvVnbuSftCWx2JLNJRqb09DoT8OwvcXb02xFR-3b7gGHP6_lL23MI-YpaGiucttJH$> > > Top 10 UK university and 54th in the world (QS Rankings 2025) > Top 5 UK university for research (THE analysis of REF 2021) > Top 5 most targeted university by top UK employers (High Fliers 2024) > > > _______________________________________________ > lustre-discuss mailing list > [email protected] > https://urldefense.com/v3/__http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org__;!!NpxR!htdOeS8P8g4PHzBcH65G_4DY52dNiVAnvVnbuSftCWx2JLNJRqb09DoT8OwvcXb02xFR-3b7gGHP6_lL23MI-YpaGoyxUWQC$<https://urldefense.com/v3/__http:/lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org__;!!NpxR!htdOeS8P8g4PHzBcH65G_4DY52dNiVAnvVnbuSftCWx2JLNJRqb09DoT8OwvcXb02xFR-3b7gGHP6_lL23MI-YpaGoyxUWQC$> _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
