Are any alerts in error_log:

grep alert /path/to/log;

Lots of:

2009/08/29 23:15:52 [alert] 8716#0: open socket #152 left in connection 105

This is probably after reconfiguraiton.

What functionality do you use - proxy/fastcgi/memcached/etc ?

proxy and fastcgi, both of which appeared to be working fine. Weirdly, on my WordPress hosts I was correctly receiving the page (PHP via fastcgi), but not some of the static files, so it would just sit there waiting for ages... perhaps keepalive requests were failing?

Static files on other hosts were working (one static html file delivered by nginx + a bunch of generated images behind the nginx proxy -- collectd).

Build differences between my 0.8.10 and 0.8.11.1 packages -> added the geoip and static_gzip modules.

(For now, I've switched back to 0.8.10, but can do more testing with 0.8.11.1 if required.)

There are signinficant changes in 0.8.11, but you case is strange: I'am testing 0.8.11 on a host with 400r/s with a lot of proxied SSIed subrequests and static files, and there is no connection leak.

Have you built any third party modules ?
