Our device atlas API (hosted in a windows service) was reporting the following USER AGENT strings (these are a few examples, there were alot more) INCORRECTLY as a "Sony Ericsson W580i". We restarted the services (which reloads the atlas file) and it stopped.

Is this a known issue for long running instances of the API's to go corrupt and start reporting some incorrect mobile device for all unknown types?

should we recycle these services to prevent this from happening? thanks!
