Comment:
I reopened this issue because this bug is still occurring after 4 months
of our 2-week development cycles. We have refactored and gone entirely to
{{{apps.get_models}}} and even reduced most all instances of
{{{field__id}}} to {{{field_id}}}, because that seems to express the bug
*less* often. We also could not tell if this was Apache so we moved
several customer environments over from Apache2+mod_wsgi to NGINX+uWSGI
(still Ubuntu). And yet the bug still occurs in *exactly* the way as
described above.
Some important things to note:
1. It occurs seemingly at random. But when it happens it will happen in
waves.
2. It occurs equally in multi-processed + single-thread or multi-processed
+ multi-threaded web server configurations.
3. Recycling Apache children or NGINX vassals quickly (every 50-150
requests) causes the bug to occur *less* but it will still occur.
4. The stacktrace is *always* the same, has remained the same, and is the
same in *every* instance. There is zero deviation.
5. It *never* occurred from Django 1.4.x to 1.7.x; but has not stopped in
1.9.9 and occurred *more* frequently in 1.8.x
Any attention at all would be most appreciated.
