high bandwidth consumption and rate limiting to 64 Kbit/sec

[Josef Templ]

I have received a warning message from EDIS telling me that our server uses too much network bandwidth.
If the limit is reached, we will have only 64 Kbit/sec for the rest of the billing period.
After that period it will be reset automatically to full speed again.
I don't know yet where this high network load comes from but I see an unusual number of guests.
I am sure I have observed this rate limiting already in the past but did not know where it comes from.

Any ideas?
