Issue Alma 8/9 increasing number of server crashes for apparently "no reason"

[Bitpalast]

We are seeing an increasing number of random server crashes on Alma 8 and 9 systems since about April 2025. It seems that the load on servers strongly increases within seconds so that the system becomes unresponsive. However, there is no traffic increase seen, no suspicious log entries, just nothing that points to a cause in websites, database or PHP usage. We suspect that the wave of updates that were delivered during the past months by Alma could have something to do with it, but it's just a guess, because that's the only thing that has changed.

My question here is whether others on Alma 8 or 9 have experienced similar symptoms lately.
