Can anyone tell me what this means and how i can prevent this possible below
overflow .
The URL is a webcam.
I tried to exclude the url from caching:

---------cut------------
acl url_cam-campus url_regex http://camara.ourdomain.net/.*
no_cache deny url_cam-campus
---------cut------------

but this does not solve the problem.

Thanks a lot for help

MfG
Michael Kaiser

There is currently a limit in how large responses Squid can handle. This
limit is around 2GB on 32-bit platforms.

This camera is most likely streaming video over HTTP, and to prevent
internal disaster Squid terminates the connection to the camera when about
2GB of data has been transferred.

There is no special action required from your part, unless ofcourse if
your users are having problems due to this.

Henrik
