Recently I’ve needed to restart nginx on my vps (which is debian wheezy)
and
it got stuck. Other services are fine but nginx not responding if there
is a
file operation involved. For example nginx -h prints out fine, but nginx
-t
is just waiting. How can I examine problem?
dmesg and messages are clean. disk and memory usage is not even %50.
This is probably not an nginx-specific error but it’s disturbing. I’ve
tried
to downgrade nginx a bit but not worked.
