Comment 4 for bug 191731

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):
