Increased memory usage


We noticed a short spike in resources yesterday around 2:30pm, visible in CPU, memory and storage usage, but memory usage didn’t get back to its original level, unlike cpu and storage.
The memory usage was around 28% before the spike, then increased to 45%, and is now staying around 38%.

Do you have any idea what could have caused this and why the memory usage hasn’t gone down?

Thanks in advance.

Hi @imhaage ,

We’re just looking into this for you and will get back to you ASAP!

We’ve taken a look at the metrics and logs, and can’t see a cause for concern at the moment.

In the past week, there have been 4 spikes in IOPS and memory usage, most likely caused by some O3 writes. After each of these, the associated memory spike comes back down. Again, in this case, it is decreasing, albeit slowly, but its nowhere near the limits.

The chart you posted is only for the past 24h, so doesn’t show the full story. Here are some charts for the past 7d:

Let me know if you have any more questions - and of course, if you notice any other problems or performance degradation.

Thank for your reassuring answer and for the screenshot.
I noticed the slow decrease, I’m relieved to know it already happened and memory usage came back down.
