Two "MIQ Server" processes running at the same time

I am using the darga miq.
The memory of host running miq is exhausted. I found there are two “MIQ Server” processes running on the host, so workers are started twice.
I try to figure out the reason, but no actions were done to miq and there were no related error logs.
Is there any possible reason to cause this?

@wangxiangyu Can you see if this PR was applied on your appliance? You can you use git am or patch to apply a patch file.
