After updating an M10 cluster from 4.4 to 5.0, the cluster is degraded and nodes are constantly going down and rolling back

We tried the 4.4-to-5.0 upgrade in 2 other clusters and all went well.
Now the 3rd cluster is unable to run steadily for some hours, and this happens to be the production one…
The other clusters (developer lab and staging) managed to update peacefully…
Can anything be done to stabilize a cluster?

Hi @Boris_Figovsky,

I recommend contacting the Atlas support team via the in-app chat support to ask if they are able to check on the version 4.4 to 5.0 upgrade for your 3rd cluster. The support team would have more insight into the cluster itself & the upgrade that is occurring.
