acess log over nfs hanging

[Jader H. Silva]

Hello all.
I've been using nginx as a reverse proxy and to write access.log files
named with variables. I am also using open log file cache.

It seems that when some processes are running in the nfs server, the share
won't allow writing for some time and I noticed all nginx workers in status
D and not processing requests.

Are all access.log writes blocking? If my nfs server shutdown in an
unexpected way, will nginx stop proxying requests to the backend or
responses to the client?

Thanks in advance
