node startup crash

Thanks for the advice, but I tried that a couple of times before 
submitting this posting.  Then I also did:

~/otp_src_R10B-4>killall epmd beam
~/otp_src_R10B-4>rm -fr /usr/local/lib/erlang
~/otp_src_R10B-4>make install
~/otp_src_R10B-4>erl -sname abc
{error_logger,{{2005,4,23},{21,41,36}},'Protocol: ~p: register error: 
~p~n',[inet_tcp,{timeout,{gen_server,call,[erl_epmd,{register,abc,35363},15000]}}]}
{error_logger,{{2005,4,23},{21,41,36}},crash_report,[[{pid,<0.18.0>},{registered_name,net_kernel},{error_info,{error,badarg}
...

The same crash.  There's not a lot of stuff running on this host either. 
  Below is the output of "ps -ax".  We can also see that epmd was 
started from the right distribution (erts-5.4.5).  This is somewhat 
annoying, as  I am not sure what else can be checked in order to 
overcome this crash...

Thank you.

Serge
