[8.202] Strange CPU-peaks in the last 2 weeks (postgres)

Hello

As you can see in the attached screenshots, our ASG320 [8.202] shows strange CPU-peaks every 15 mins which last 2 mins each time and are caused by postgres.

This behaviour began about 2 weeks ago and increased the CPU-usage from under 50% to over 75%.

I opened an ticket at Astaro (premium support) but they didn't find anything in the last 3 days.

Does someone know these symptoms and can tell me how to fix it ?

Node1 is slave at the time of the screenshot, node2 is master (3rd screenshot)

Here's the process, which causes the CPU-peaks every 15 mins:

postgres 16875 93.2 3.4 182000 136808 ? Rs 15:03 0:18 postgres: reporting reporting [local] SELECT

It indeed is some kind of bug. Astaro support already installed the corresponding part of the upcoming update on my box and now the peaks are still there but nowhere near as bad. See my CPU Usage of yesterday. You can still notice little peaks every 15 minutes but I can deal with that.

We still see these CPU-spikes on our systems. Now I asked Astaro support to rollout this hotfix to our systems too.

We'll see...
