You mean you log rotation script you've posted earlier?  It 
shouldn't cause problems, if it does - this means there is a bug 
somewhere.  And I think I've found the one you are seeing, please 
try the following patch:

diff --git a/src/event/ngx_event_pipe.c b/src/event/ngx_event_pipe.c
--- a/src/event/ngx_event_pipe.c
+++ b/src/event/ngx_event_pipe.c

     if (p->length == 0) {
         p->upstream_done = 1;
+        p->read = 1;
     }

     if ((p->upstream_eof || p->upstream_error) && p->free_raw_bufs) {
