After deploying change to magento cloud (2.4.3p3) our servers are hitting 100% CPU, which makes the whole system unresponsive and inaccessible. It seems to last random amount of time can be more than 30 minutes before the system recovers. Is this kind of behaviour normal?
Happens consistently after deploying changes to staging & production environments but also, clearing a single cache (even just for CMS updates) results in making our production environment unresponsive due to high CPU usage. This means that we can’t actually deploy to production without significant downtime currently.
I’ve found many threads about high usage on cache but most seem to be related to people disabling cache for development environments.
Are there any settings/configuration that I can check which have a large impact on cache performance?
