Try using

   error_log /var/log/nginx/error.log notice;

here, it will instruct nginx to log at "notice" level.  This 
includes system events like controlling signal.  I.e. on getting 
SIGINT nginx will log something like this:

2011/10/10 23:19:32 [notice] 24178#0: signal 2 (SIGINT) received, exiting
2011/10/10 23:19:32 [notice] 24178#0: exit

I suspect the cause is some broken log-rotation script which kills 
nginx instead of instructing it to reopen logs.

(This is completely unrelated to "upstream sent too many data" 
messages though.)
