did freese in creating a database cluster

Hello, PostGreSQL-Masters

<<System>>
PostGreSQL: 7.4.30 the postgres-installer ( postgresql-7.4.30.tar.gz)
OS: AIXv5.2 TL09 (POWER5)
Machine: 9119-590(1LPAR)

<<Status>>
I have got the following status or problem with an initdb command,
which is "initdb -D /usr/local/pgsql/data -d".
The point of "selecting default max_connections..." did freeze,
and the status is the same although I have waited for 24 hours.

<<Question>>
1. What was the situation happend in creating a database cluster?
2. Would you please give me solution or workaround for this status?
