Avia avia-merged-styles maxing out RAM and CPU

Hi,

Our site went down this morning as something maxed out resources.

Siteground looked into it and identified the issue as avia-merged-styles. I have copied the log output below.

I’ve disabled CSS Merging and compression and flushed SG cache and Coudflare caches.

We have Minify JavaScript Files enabled in SG Optimiser but Combine JavaScript Files is disabled.

Is there anything else we should do to avoid this happening again?

We’re using Enfold 4.7.5.

With thanks

Regards

Phil
