Unable to Navigate the Portal while Downloading Folders or Files

[pddro-Vestas]

Hello everyone,

Raised issue here based on the discussion in https://discourse.openondemand.org/t/unable-to-navigate-the-portal-while-downloading-folders-or-files/4826

When I initiate a download operation in the Files app, I am unable to navigate the portal. It hangs and eventually fails with proxy error. As soon as the download completes, I am able to navigate without any issues. The issue is similar to the one described below.
Proxy error during downloading folders and files - Get Help - Open OnDemand.

It happens for the download of both files and folders (folders are zipped automatically). The download starts instantly and I can follow it in the downloads tab of my browser.

Please note that this is specific for download operation. Upload operation works correctly.

Could this be due to an issue in nginx the configuration? To me it looks like the download is blocking the PUN process, which is unable to process any other requests until the download completes or is cancelled.

Tested with OnDemand version 4.1.4, running in OS AlmaLinux 9.7, Microsoft Edge browser and the download and upload limit is set to 20GB.

Thanks,

Best regards,
Pedro D.R. Santos

I said this on discourse, but just posting here for completeness.

Seems like passenger will only boot up multiple threads in the enterprise version. So getting parallel threads here may be tricky.
