We're seeing operational issues in the sso servers when they are brought up in r/o mode.
I'll attach more backtraces to the bug, but briefly:
encodings.utf_8 has its global variable codecs set to None, which is something the VM does when it thinks a module is being finalised, to make things cleanup safely and racefree.
This patch http://bugs.python.org/file15318/modcleanup.patch in http://bugs.python.org/issue6551 shows a similar issue that Python itself had in its test suite with near-identical symptoms.
My theory is:
14:11 < lifeless> I'm thinking a thread that starts up and does some naughty 'probe'
14:12 < lifeless> and thus sometimes it wins, and the system breaks
14:12 < lifeless> and other times it loses and the system doesn't break
Which sounded plausible to spiv, so I think bears investigating. |
We're seeing operational issues in the app servers when they are brought up in r/o mode.

It happened with several (but not all app servers) and restarting them manually usually work.
