Tried a branch of all revisions, "bzr branch svn+http://...", using bzr 1.2 and it still ran out of memory after 3.5 hrs and close to 9200 revision_ids were added. However, as I mentioned earlier, there is a workaround, as I am able to create a branch by pulling about 1-2k revisions at a time, "bzr branch -r1000 svn+http://... project; cd project; bzr pull -r2000; ...". I still can't tell if the problem is in bzr, bzr-svn, or the subversion bindings. Let me know if there is any diagnostics or tests you'd like me to execute. The tracebacks when it dies are inconsistent, since they report when the process runs out of memory, not who's taking it all. Here's the tracebacks from the full branch attempt (a mix of console and .bzr.log output): bzr: ERROR: bzrlib.errors.KnitCorrupt: Knit corrupt: While reading {svn-v3-trunk0:3282bf91-d132-0410-b1ef-d2f8e70e1952:trunk:9168} got MemoryError() 13224.904 Traceback (most recent call last): File "/usr/lib64/python2.4/site-packages/bzrlib/commands.py", line 834, in run_bzr_catch_errors return run_bzr(argv) File "/usr/lib64/python2.4/site-packages/bzrlib/commands.py", line 790, in run_bzr ret = run(*run_argv) File "/usr/lib64/python2.4/site-packages/bzrlib/commands.py", line 492, in run_argv_aliases return self.run(**all_cmd_args) File "/usr/lib64/python2.4/site-packages/bzrlib/builtins.py", line 908, in run accelerator_tree=accelerator_tree) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/remote.py", line 75, in sprout result_repo.fetch(repo, revision_id=revision_id) File "/usr/lib64/python2.4/site-packages/bzrlib/repository.py", line 949, in fetch return inter.fetch(revision_id=revision_id, pb=pb, find_ghosts=find_ghosts) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/fetch.py", line 716, in fetch self._fetch_switch(needed, pb, lhs_parent) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/fetch.py", line 673, in _fetch_switch reporter.finish_report(pool) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/errors.py", line 110, in convert return unbound(*args, **kwargs) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/transport.py", line 271, in finish_report self._baton, pool) File "/usr//lib/svn-python/libsvn/ra.py", line 783, in svn_ra_reporter2_invoke_finish_report return apply(_ra.svn_ra_reporter2_invoke_finish_report, args) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/fetch.py", line 386, in close_file self._store_file(self.file_id, lines, self.file_parents) File "/usr/lib/python2.4/site-packages/bzrlib/plugins/svn/fetch.py", line 467, in _store_file file_weave.add_lines(self.revid, parents, lines) File "/usr/lib64/python2.4/site-packages/bzrlib/versionedfile.py", line 122, in add_lines left_matching_blocks, nostore_sha, random_id, check_content) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 925, in _add_lines parent_texts, left_matching_blocks, nostore_sha, random_id) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 993, in _add left_matching_blocks) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 856, in _merge_annotations reference_content = self._get_content(parents[0], parent_texts) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 905, in _get_content text_map, contents_map = self._get_content_maps([version_id]) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 1085, in _get_content_maps record_map = self._get_record_map(version_ids) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 1049, in _get_record_map for component_id, content, digest in \ File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 2496, in read_records_iter content, digest = self._parse_record(version_id, data) File "/usr/lib64/python2.4/site-packages/bzrlib/knit.py", line 2401, in _parse_record "While reading {%s} got %s(%s)" KnitCorrupt: Knit corrupt: While reading {svn-v3-trunk0:3282bf91-d132-0410-b1ef-d2f8e70e1952:trunk:9168} got MemoryError() bzr 1.2.0 on python 2.4.3.final.0 (linux2) arguments: ['/usr/bin/bzr', 'branch', '--verbose', 'svn+http://192.168.4.23/repos/rocc/branches/rdo_0_1', 'bzr.rdo_0_1'] encoding: 'UTF-8', fsenc: 'UTF-8', lang: 'en_US.UTF-8' plugins: bzrtools /usr/lib/python2.4/site-packages/bzrlib/plugins/bzrtools [1.0.0] gtk /usr/lib/python2.4/site-packages/bzrlib/plugins/gtk [0.93.0] launchpad /usr/lib64/python2.4/site-packages/bzrlib/plugins/launchpad [unknown] multiparent /usr/lib64/python2.4/site-packages/bzrlib/plugins/multiparent.py [unknown] svn /usr/lib/python2.4/site-packages/bzrlib/plugins/svn [0.4.7] *** Bazaar has encountered an internal error.
