Sudden High CPU with GC

[nuwancs (Nuwan Chamara)]

Hi Team
Please refer to the screenshot and we observe high CPU spikes with the GC. Please help us resolve this.
ELS v 7.5.2
RAM: Total 32 GB, 16GB allocated to ES

It's a 7 node cluster

That overall looks good. I do not see any problem that needs resolving.

Thank you @Christian_Dahlqvist for the response, but our customer isn't happy as this behavior regularly generates high CPU alerts. So you idea is we can ignore it safely right?

7.5 is EOL, please upgrade.
