I don't know if it's something already known and to be fixed but I have very rare exception of this kind. It seems the .resources file is in use by concurrent processes:

Hallo Michael this could very well be the "issue" behind it.
It would be nice to have the virus scan user uploaded content btw I guess. maybe just exclude the resource/cache folders would be a better option.
I'll try. Thanks for your precious hint! What is the 0-system in the portals dir btw? I never noticed that -system stuff in 7.2.2 ?

Hi Guys,

was this resolved as a anti virus issue?

I get the same issue, but we are not running any anti virus on the web server as it is an internal one.

System.IO.IOException: The process cannot access the file 'I:\inetpub\.................data.resources' because it is being used by another process.
