[Forums] Error invalidating espace caches

Hi Patrice

Don't know if you contacted Support yet, but from the error message:

System.IO.IOException: The process cannot access the file 'C:\Program Files\OutSystems\Platform Server\CacheControl\cacheFile_e20.osc' because it is being used by another process.

it seems some process other than the platform is accessing a file, and preventing the platform from changing it. The number 1 cause for this type of issue is anti-virus - so I'd suggest looking into and applying the measures here before anything else:
