Hi mehargags, thanks for pointing this out,
Luckily i already monitor those stats in detail.
I have round about 40 WordPress Sites on each Server, most of them very low traffic, some get a few thousand visitors a day. The Servers have a Gbit connection tho. There are not used for heavy downloads but only for serving normal websites.
Here are the stats from the last month, where i did not do any restarts. For me everything seems pretty normal, also when you zoom in to just a day. Do you think otherwhise?
Any other ideas? :)
