CPU spikes from Elasticsearch since upgrading to Zenarmor 2.7.1. Anyone else?

[mlenje]

Since upgrading to Zenarmor 2.7.1 on Oct 26, I've had two short CPU spikes on my OPNsense box. I've never had one before the upgrade.

When: Oct 27 at 02:15 and 22:15

What: each lasted about 4 minutes, with CPU at 90%+ and the load average around 8–9. It recovered on its own.

Source: the Elasticsearch java process (local Elasticsearch 8.11.3)

Ruled out: network traffic and cron jobs

Setup: OPNsense 26.7, i7-3770 with 32 GB RAM, local Elasticsearch reporting database.

I'm monitoring to see if it repeats.

Has anyone else seen something similar since moving to 2.7.1?
