I've been troubleshooting a high CPU load on a VPS. We moved over to this VPS a few months back, and it's been fine. Nothing has been changed on there. All of a sudden, we are getting high CPU usage from ElasticSearch (even when XF is configured not to use it???) I disabled it, and the load went down, re-enabled it, and it's gone high again There have only been 5 posts on the forum so far today, with a total of 155,000 posts. I've upgraded from ES 0.90.7 to 0.90.9 (had errors with .10) and it still the same. Config has remained the same (same ES setup as my own server). Anyone else come across something like this before?
