riak not starting, Reason: {badmatch,already_exists}

Hi Dan,

There are no other beam processes running.  The only thing running that is related to riak is "riak/erts-5.7.5/bin/epmd -daemon".

Hi David,

Can you check to see if you have any beam processes running (perhaps another Riak instance)?

Hi, one of the riak nodes is not starting.  I am getting  {badmatch,already_exists} in sasl-error.log.

At first, I was getting 'eaccess' errors, so I changed all of the files to be owned by "root:root".  Now, I am getting,

In, erlang.log.1, I see:
[{application,riak_kv},{exited,{shutdown,{riak_kv_app,start,[normal,[]]}}},{type,permanent}]/home/me/dev/poc/riak/riak/rel/riak/lib/os_mon-2.2.5/priv/bin/memsup: Erlang has closed.
Erlang has closed
{"Kernel pid terminated",application_controller,"{application_start_failure,riak_kv,{shutdown,{riak_kv_app,start,[normal,[]]}}}"}

Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,riak_kv,{shutdown,{riak_kv_app,start,[normal,[]]}}})

In my etc/vm.args, -name riak at<mailto:riak at> (which is a unique name).

Any ideas on why I cannot start riak?
