I have seen very similar behavior, and never resolved it but mentioned what I’d found here:

> environment: OOD 4.0.8 unpopulated dev system hyper-v VM selinux disabled cgroupsv2 enabled no upload-limit mods in /etc/ood/config/apps/dashboard/env I’m seeing an issue that seems very similar to [this March 2024 report](https://discourse.openondemand.org/t/large-uploads-failing-ood-3-0-1/3315) about large uploads failing with OOD 3.0.1. However my “large” uploads are only ~1.5GB, and the problem seems isolated to uploading to our /scratch fs (which is an NFS export of a bare metal lustre mount to our Vast system). About the error: filemanager’s upload dialog ev…

Frustratingly, the cutoff for what filesize was too big was never written in stone – sometimes a given ~1.5gb file would upload with success, other times it would (appear to) fail.

I had a theory that it had something to do with my /tmp or /var (lvm-)filesystem filling up since I discovered a given upload will eat up space on both. This didn’t seem to be the root issue for me (at least with the brief investigation I did) but maybe worth checking if it’s the case for you: [PSA: File Manager uploads use both /var and /tmp space](https://discourse.openondemand.org/t/psa-file-manager-uploads-use-both-var-and-tmp-space/4736)

My example watch-script is admittedly hard to read but the gist of it is a single upload temporarily stores _three_ copies, like:

- /proc/1386416/fd/8 =\> / **var** /tmp/ondemand-nginx/USERID/client\_body/0000000001 (deleted)
- /proc/1795862/fd/10 =\> / **tmp** /PassengerTeeInput-1l86ohu (deleted)
- / **tmp** /RackMultipart20260219-1795862-wimnh4.zip
