Radius Help

We are having trouble getting our radius server to connect to Oracle. It was connected last week and we stopped the process due to excessive database connections (an unrelated application issue) and now when we attempt to start it the last logged statement is "rlm_sql (sql): starting 0 rlm_sql (sql): Attempting to connect rlm_sql_oracle #0". Any ideas on how to see what's hanging up at this point? The database is on a remote server but I can ping that server with the host name used in the radius configuration. Thanks, Darrell
