ldapmodifyx -d 1 -h localhost -D 'cn=Manager,cn=config' -W -f /var/tmp/ldif

Getting the following error
res_errno: 80, res_error: <failed to reopen database, rc=22>, res_matched: <>
ldap_free_request (origid 2, msgid 2)

ldap_modify: Other (e.g., implementation specific) error (80)
additional info: failed to reopen database, rc=22

Going through the list lead me to believe that changes will be applied after
the restart? but didnt say it causes an error. Also does olcDbNoSync play a
role here ?
The change is applied immediately, there should not be any restart required. Unfortunately, it seems like the changes you applied were invalid for the version of BerkeleyDB you're using. Your LDIF worked perfectly fine for me, using BDB 5.3.21.
Another possibility is that the directory you specified for set_lg_dir was invalid, didn't exist, or you didn't have permissions to write it. One further possibility is that you were changing this value - in that case, you need to make sure to manually move all of the BDB logfiles from the old location to the new location first, otherwise BDB won't be able to find them and it will think the BDB environment is corrupted.
Using the -d debug flag on the client doesn't tell you anything useful though, you need to use -d on slapd to see what the actual error was.
