You don’t say what RAM the server instance has. I used to get this also when running without sufficient RAM. Currently I use T2.medium (4GB RAM) for my rancher-server and it is solid.
The server has 32G, with that said, it has many other VMs and is actually under resource constraints (that’s a home lab environment), so it might the the explanation right there
No problem since I disabled the ballooning driver in ros vmware tools, time for a lab upgrade I guess!
With that said, it’s interesting how unrelated conditions at first sight happen to be the cause of the problem. In my candid mind, java and ballooning would just play along like good kids but they don’t. Even though my lab is overallocating RAM, to some extend, it’s often the case with virtualization, and ballooning, though indicative of a memory issue, should not cause that kind of issues.
I wonder if the official vmware tools would have the same effect.
