You had i586 running on a CentOS / RHEL system ? RHEL is not designed to 
run on i586 architecture, although you can build yourself a kernel for the
i586 arch. Even with a i586 kernel though, GLibC NPTL supported does not 
work on anything less than an i686 CPU. BDB usually relies on NPTL for 
process-shared mutexes, so if you're using BDB on non-NPTL system all hell 
will break loose because locking will be fubar.
