Django Hanging with older Pylibmc

I notice this has been reported before on ticket #15655 I've got a bit further on the diagnosis.

Using the Debian Squeeze default Pylibmc which is version 1.1.1 then Django will freeze with no logging whatsoever as to the problem. However upgrading Pylibmc to the latest version 1.3.99 and everything is fine.

It would be good to update the documentation to make it clear that a newer version of Pylibmc is required.

Do you know which version of pylibmc fixed the problem?

If this issue is well documented, we could add a check on the version of pylibmc and refuse to start with a buggy version.

I suppose it's, which is a duplicate of

This is the "Fixed GIL issues" item of version 1.2.0. So the requirement would be pylibmc >= 1.2.

I don't know exactly how often the problem happens. Is it systematic under mod_wsgi?

Resolution: needsinfo
Status: newclosed

Closing as needsinfo since we haven't gotten further clarification about the issue and newer versions of Debian are now available which presumably have a more recent version of pylibmc. If someone would like to provide a patch, please reopen.
