Hi,

It seems that Nginx does not flush the log buffers to disk on reload but  
it would be really helpful if it could. Is there any trick to flush the  
buffers to disk on reload?

Thanks,  
Markus

Log buffers are flushed by a shutting down nginx worker process  
once there are no more requests in progress and it’s going to  
exit. If it’s not enough in your use case, you may use logrotate  
signal (USR1) flush log buffers at any time you want.
