Hi,

we got an OutOfMemoryException. The Applicationpool stops every time and we don't know what went wrong.

Please help.

Here is the detailed error message:

This looks like a bug with 51Degrees provider that we use for mobile device detection.  I know there were some issues in earlier releases and recommend upgrading to the current 7.3.1 release which has a version of the 51Degrees provider which is faster and uses a smaller memory footprint.

please check /app_data folder for large temp files and delete it.
Are you using 3rd party modules? how many websites, pages, modules and users are there in your Installation?
