The error 22 is almost always an issue with:
1) Mismatch between code, libberkeley-db, BDB DLL assumptions about BDB version
Are you sure your code is using constants for BDB-4.7 (set in
my-config.sexp)
2) CFFI/UFFI
3) Sometimes I've seen this be a 64-bit vs. 32-bit issue
Your db-env-set-max-locks error seem to indicate an error in category #1. Are
you certain that the code knows you're using BDB-4.7?
