[issue15765] test_getcwd_long_pathnames (in test_posix) kills NetBSD
Charles-François Natali added the comment: This doesn't look thread-related: load: 0.50 cmd: python 10630 [runnable] 0.27u 13.07s 46% 10976k load: 0.87 cmd: python 10630 [runnable] 0.27u 94.24s 98% 10976k See the huge system time? This probably means that the kernel is struggling with path name resolution, although that's surprising because 4099 is a reasonable limit. Do you have something like strace or truss on NetBSD? The first thing to try could be to lower the limit, and see what happens, but it's really likely a FS scalibility limit you're hitting (altough, once again, that's really surprising given the reasonable limit). Are you running those under VMs? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15765 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15765] test_getcwd_long_pathnames (in test_posix) kills NetBSD
Trent Nelson added the comment: Looks like this is a duplicate of issue 9185. The fix used for that just needs to be extended to cover NetBSD as well. See proposed patch. I'll commit this to 2.7 in a day or two if there are no objections.

Stefan Krah added the comment: The timeouts on NetBSD and OpenBSD are very likely related to bugs in the user-space thread libraries. See also #8714.
