since this morning I have an unusual high CPU usage of my Astaro (v8.306) httpproxy process. I'm not able to determine the cause in any more detail - probably someone else can help.
Shortened top output looks something like this:

CPU usage graph has been attached to this post.
Does anyone else have this issue or knows how to dig deeper and find the cause of this sudden rise of activity?
ASG runs on ESXi host with 4 vCPUs and 4 Gigs of RAM. The number of concurrent network connections and traffic is about the same as yesterday and the days before. Configuration has not been changed today.
The only thing I have done is I flushed the Proxy Cache when I noticed the high load.

Alex
