> Hi Jerome, I may be hitting a similar issue with 0.8.10.

I confirm that the bug is having a similar issue with 0.8.10. I've
just tested it.

By the way, the bug does not appear if I add 404 page to
proxy_cache_valid directive:

proxy_cache_valid 200 302 404 30s;

An other solution is to remove the "updating" option for the
"proxy_cache_use_stale" directive.

I'm looking into the code to try to find a solution.
