Chef Server goes to idle state every day at random times


I have installed latest chef server on an EC2 instance(t2.small with 10 GB HDD), it was working fine for the first few week, and it has 6 nodes currently. Since last two weeks the server goes to idle state every day. I have to restart it to bring it back online. couldn’t find any logs on the server after restart.
Does this happens because less CPU on t2.small?

Any helps would be appreciated.

Chef Server should really have more than 4GB of RAM. A t2.small has only 2 GB RAM so you’re probably running into the kernel OOM killer. I’d suggest at least a t2.medium for a test deployment.

changed the instance type and its working smooth. Thanks @jdunn
