Can't replicate using the instructions above.

I have tried various attachments with various names in different languages with weird characters and still nothing. Tried on production and on staging servers and with different browsers.

Added some more error logging on the backend during attachment upload, hopefully this will allow us to narrow down where the issue is originating from.

This is still happening, no interesting save error logs. Researching one user, they have saved attachment uploads on multiple different backend servers on the same day (in the same hour). As we direct users to servers based on their IP, can only assume somehow their IP is changing rapidly.

I have created a patch for our HAProxy install and sent it to be reviewed/installed

HAProxy update deployed

Reopening thus as one user has re-reported the issue (details available internally).
