Question:

When running dbloc2, origins and arrivals are not matching and there are many error messages.

Answer:

Try the easy thing first and run dbloc2 with the -r option:

% dbloc2 -r your-database

If the problem still persists, you likely have some problems in the assoc table. Run dbverify to see what the problems are; use dbe, dbset and dbdelete to fix the problems. More importantly, figure out how the inconsistencies arose in the first place, and fix that.
