Problem scenario: You recently installed Chef server on a Linux t2.micro instance (an AWS virtual server with 1 vCPU and 1 GB of RAM). You ran this command "chef-server-ctl reconfigure" and received this error:
"Errno::ENOMEM occurred in delayed notification: runit_service[opscode-solr4] ( private-chef::opscode-solr4 line 37) had an error: Errno::ENOMEM: Cannot allocate memory - fork(2)"
What should you do?
Root cause: A t2.micro instance has insufficient RAM. You will need a server with more memory.
Try this command: free -mh
The results of the above command will look something like this if there is enough memory:
total used free shared buff/cache available
Mem: 3.5G 1.1G 217M 68M 2.1G 2.0G
Swap: 0B 0B 0B
You need a server with at least 4 GB of RAM. Chef's hardware requirements are 4 GB. See this Chef document for more information. To install a standalone Chef instance, follow these directions. To add RAM to a VM click here for AWS resizing directions or here for GCP resizing directions. For directions on adding or configuring virtual memory, see this posting.
