This could happen if 4 and 6 occur in different threads/processes but since the txn_dir_cache is per-thread or per-svn_fs_t any cache from a MKCOL will not be visible to MERGE. So there is no txn_dir_cache when apache/mod_dav_svn runs the pre-commit and so no cache to become out-of-date. -- Philip Martin | Subversion Committer WANdisco // *Non-Stop Data*
