My current test with svn trunk & apache+mod_dav_svn 1.6.12 does not reproduce this issue. What I am seeing is that svn is using a lot of memory, up to 1GB. Currently looking at the root cause there. First clue: many directories are not closed until the call to close_all_dirs in libsvn_ra_serf/update.c:finish_report. This means that for the most part of the checkout, the associated info object is kept in memory. >> Another checkout error to add to list of ways it can fail: >> >> A wc/86/subversion/tests/cmdline/import_tests_data/import_tree/DIR1.noo >> A >> wc/86/subversion/tests/cmdline/import_tests_data/import_tree/DIR6/DIR7/DIR8.noo >> A wc/86/subversion/bindings/swig/proxy >> ../src/subversion/svn/checkout-cmd.c:168: (apr_err=175009) >> ../src/subversion/libsvn_client/checkout.c:179: (apr_err=175009) >> ../src/subversion/libsvn_client/update.c:579: (apr_err=175009) >> ../src/subversion/libsvn_client/update.c:440: (apr_err=175009) >> ../src/subversion/libsvn_wc/adm_crawler.c:858: (apr_err=175009) >> ../src/subversion/libsvn_ra_serf/update.c:2676: (apr_err=175009) >> ../src/subversion/libsvn_ra_serf/update.c:2672: (apr_err=175009) >> svn: E175009: Missing update-report close tag >> > > From your previous report I noticed the 406 response that serf isn't > handling, at least serf doesn't support a response coming in while the > matching request wasn't completely sent yet.
