Hello everyone,

after upgrading one of our repositories from DSpace 9.1 to 9.2, we started 
receiving user reports about intermittent issues during the submission 
process.

Symptoms:

   - 
   
   When a user clicks Save in the submission UI, the caption changes to 
   “Saving…” and stays in that state indefinitely.
   - 
   
   In some cases, the same behavior happens during autosave — the UI also 
   shows “Saving…” and never recovers.
   - 
   
   The page must be refreshed to continue working.
   - 
   
   After refresh, some of the recently entered metadata may be lost.
   
Important detail:
Based on user feedback, this usually occurs when a user spends around 10 
minutes editing metadata fields before clicking Save.  

These issues did not occur in version 9.1. 

Environment / configuration:
OS: Debian 13
PostgreSQL 17
Solr 9.10.0
OpenJDK 21.0.9
Node.js v22.14.0
Tomcat 10
Apache HTTPD as reverse proxy

Questions:

   1. 
   
   Is this a known issue in DSpace 9.2, especially related to longer 
   metadata editing sessions?
   2. 
   
   Were there any changes to authentication, XSRF handling, autosave, or 
   submission save logic in 9.2 that could cause this behavior?
   3. 
   
   Has anyone observed similar behavior where Save or autosave hangs 
   intermittently and data is partially lost after a page refresh?
   
Any pointers or insights would be greatly appreciated.

Best regards,
Dmytro
