-B is specified in units of database blocks, so at a minimum we need to know your DB block size. Find your last database start in the log file (a "(333)" message) and copy the next 70-80 lines (up to "Database connections have been enabled."). Paste that in here within CODE tags. That will help to assess what you might want to change in your startup parameters. Also, the output of "proutil dbname -C describe" would help.
