Kevin,
Strange indeed but definitely unrelated to the listener itself.
ORA-12154 is definitely a client-side error - you need to find the
service name before hitting any listener. It probably is a names
server-related problem.
Concurrent connections are limited by the 'processes' init.ora parameter
and the (Unix) maximum number of processes per login, whichever is
smaller.
