I have a NAS drive with ~16200 pictures and 154 directories on it.  I am synchronizing and sometimes the synchronization completes just fine.  Other times I see that Nginx times out with a I think it was a 504 error.  I cant seem to recreate the issue at this time.  Is there something in the PHP config, maybe a memory setting that I can increase to avoid nginx timeouts?  The server has a ton of memory - and most of it is unused.  Any ideas will be helpful.  Thanks in advance.

Cheers,

Noah
