My guess is that this is the problem:  https://github.com/ManageIQ/manageiq/pull/8707

We changed the server setproctitle to "MIQ Server" but the "rake evm:start" (start evmserverd) mechanism which prevents multiple server processes was looking for evm_server.rb.  I'll try to get that PR merged and we can try backporting it to 5.6 to see if it helps.

    evm.pid / process existence is the safe way to ask if we're running?
    
    When we changed the process title using setproctitle to "MIQ Server" [1], we broke
    rake evm:start's detection of a previously running server.
    
    While a process title/command line is somewhat helpful to check, only the server
    should be writing to evm.pid so checking for a process from evm.pid is enough.
