Title: One line description

Description:
I started envoy with root user by mistake. I killed it.
Then when i start envoy again with my own user, it says:
[!184 06:42:56 ~]$ [2018-10-10 06:42:56.702][23046][critical][assert] source/server/hot_restart_impl.cc:62] panic: cannot open shared memory region /envoy_shared_memory_110 check user permissions. Error: File exists

Which file should i remove before i start envoy with my own users? Thanks
