Hi Gladys.
I doubt if number 5 is your problem, as it would not have "worked for a
while" if that was the case. The only thing that comes to my mind is
ensuring that disableUploadTimeout="true" on the Tomcat connector is set.
Good Luck

Hello DSpace technical community,
I am managing a DSpace 7/8 installation and have been encountering a
recurring problem whenever users try to upload PDFs. The interface
always returns a “upload failed” message. After numerous attempts to
diagnose and fix this issue, I’m reaching out for your guidance. Below
is a summary of the troubleshooting steps I’ve performed:
1. **Assetstore regeneration** – On version 7, I tried deleting the
`/dspace/assetstore` directory and regenerating it. Interestingly,
this fix worked for about a day, but then the “upload failed” error
returned.
2. **Permissions and ownership** – I confirmed the permissions and
ownership of `/dspace` and all subdirectories (including the
assetstore). The Tomcat user owns these directories, and file system
permissions are open enough to allow writing. Running manual tests
(e.g., writing files to the assetstore as the Tomcat user) works
without issue.
3. **Config checks** – I verified that `assetstore.dir` and other
relevant paths in `dspace.cfg`/`local.cfg` point to the correct
locations. I have also ensured that there is sufficient disk space and
no file system quotas preventing uploads.
4. **Review of logs** – I examined the DSpace logs (`dspace.log`) and
Tomcat logs. The messages show an error whenever files are stored, but
there is no obvious stack trace pointing to permission issues. The
error message is similar to: “Failed to upload file; upload failed.”
5. **System-level investigation** – I looked into whether the problem
could be related to the service configuration. Some documentation
suggests that Tomcat’s systemd unit may be sandboxed and unable to
write to the assetstore directory unless configured with
`ReadWritePaths=/dspace`. I haven’t yet edited the systemd unit file,
as I’m seeking confirmation that this is the right direction.
At this stage, I’m uncertain what is causing the upload failures. I
would appreciate any suggestions on further diagnostic steps or
specific configuration changes to resolve this problem permanently.
Thank you in advance for your time and expertise.
Best regards, Gladys
