Server returns 500 error on upload. Fixed by restarting openfire service but problem keeps appearing later.

[hakakou]

Using OpenFire 4.6.4, HTTP File Upload 1,1.3, on Windows Server 2016.
I'm using a converse.js client to upload files in the chat. Almost always it's succesful, however sometimes the response from the server is a 500 error. In the openfile logs, under the "All" tab, I see lines like:

2021.09.06 02:03:37 nl.goodbytes.xmpp.xep0363.Component - Entity 'xic.support@chat.xxx.com/converse.js-44692399' tries to obtain slot.

--- nothing else after about the upload

In the "Warn Tab"

2021.09.06 02:03:37 org.eclipse.jetty.server.HttpChannel - handleException /httpfileupload/0f341d6d-564e-45d3-b0a2-1648f6f25450/DSC5659.jpg java.nio.file.NoSuchFileException: C:\Windows\TEMP\xmppfileupload3257014815371578219\0f341d6d-564e-45d3-b0a2-1648f6f25450

The problem is that if I start getting these errors, then they appear indefinitely on every upload. However problem is fixed immediately if I restart the openfire service.

For example, if I restart the service, the upload works fine, and the logs are instead:

2021.09.06 02:08:13 nl.goodbytes.xmpp.xep0363.Servlet - Processing PUT request... (XX.XX.112.23 submitting to /httpfileupload/8c8018b8-1e1b-4ad3-bb68-4fa95a9293ec/DSC5659.jpg)

Any hints on how to fix this problem? After each service restart, the uploads work again for perhaps 24 hours, until this problem starts appearing again. I have checked permissions on c:\windows\temp, and this is not the problem.

Hmm... I wonder if this is caused by your operating system automatically purging the temp folder that is being used.

You could try to use a different directory by adding this system property to Openfire plugin.httpfileupload.fileRepo (you will need to restart the plugin afterwards).
