nginx-extras (1.4.1 Ubuntu precise) cache loader/manager issue

[nmarques]

Dear people,

I used for a while the nginx-extras 1.4.1 for Ubuntu 12.04 LTS (precise); I
used this package since it supported 'more_clear_headers' which was useful
to hide some headers (LifeRay headers). As you have guessed, I'm using nginx
for reverse proxying and from a while for caching (as an alternative to
varnish).

I've run into a strange problem; If I use nginx-full I have no problems
what-so-ever and the cache manager/loader do run properly and it works like
I charm (but I can't hide the headers! any alternative method is most
welcome); If I use the nginx-extras the cache manager/loader is utterly
broken and I get this output:

2013/08/14 01:14:18 [info] 30478#0: Using 32768KiB of shared memory for push
module in /etc/nginx/nginx.conf:52

2013/08/14 01:14:19 [alert] 30490#0: cache manager process 30499 exited with
fatal code 2 and cannot be respawned

Now, either this build has some addon which breaks nginx (?) or the build
somehow is broken in some weird way...

Can someone please test this and checkout if everything is OK with those
binaries? Any feedback is most welcomed.

PS: By the way, awesome cache performance (over a ramdrive)!
