Description
Yesterday we used 42 CPU cores on our server. We had a lot of traffic and we plan to install 62 cores. But with 42 cores nginx has problems to open the socket file or the 127.0.0.1:9000 port.
Scaling our server down to 32 cores everything works fine.
We got the following log entries:
socket version:
[error] 5172#0: *215354 connect() to unix:/tmp/php5-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream
port version:
[error] 10178#0: *598467 upstream timed out (110: Connection timed out) while connecting to upstream
Is there a limit and how is the limit? If there is a limit, can you set the limit up?
Note:
See TracTickets
for help on using tickets.
Your upstream server is overloaded, not a bug in nginx.
