Are you *really* using the same lg_dir and tmp_dir for both databases?

"The DB_CONFIG file I use in both database directories" where DB_CONFIG is a 
link to http://ww2.whidbey.net/davidke/DB_CONFIG .

http://ww2.whidbey.net/davidke/DB_CONFIG contains:

set_cachesize  0 134217728 1
set_lg_dir /var/log/bdb
set_tmp_dir /var/log/bdb
set_lg_regionmax 262144
set_lg_max 104857600
set_lg_bsize 2097152
# set_flags DB_TXN_NOSYNC

Having transaction logs for different DBs in the same directory sounds like a 
recipe for many bad things ....
