It may be an indication of a bug in the JUPNP library, OH Core, or an OH addon, but we would need to see a stack trace to find out which..

There was something odd going on with my installation. I think the SD card is playing up. I installed a backup and everything seems to be back in order. The logs kept crashing…

Hi, That warning is usually harmless and comes from a UPnP device advertising an invalid device type string on your network.
To mute it, add a logger entry for org.jupnp.util.SpecificationViolationReporter and set it to ERROR (or OFF) in your log4j2.xml / console logging config.

Example:
log:set ERROR org.jupnp.util.SpecificationViolationReporter

This will suppress the repeated WARN messages without affecting normal operation.

Hope this helps
