Hi, I have a question.
We have the system which the following structure is used:
Nginx <----> CGI interpreter <----> yumapro Netconf server
Multiple CGI interpreters are created and used through the settings below.
spawn-fcgi -s /var/run/fcgiwrap.socket -F 5 -- /var/www/yang-api/restconf
Nginx <----> CGI interpreter <----> yumapro Netconf server
CGI interpreter
CGI interpreter
CGI interpreter
CGI interpreter
A typical restconf set/get operation is used while appropriately load sharing through these five CGI interpreters, and when the set/get operation is completed, we can see that all used sessions are closed.
However, once a server-sent-event session is created, one CGI interpreter continues to wait in a blocking state for an event to occur from yumapro, so one CGI interpreter cannot perform other set/get operations.
In the above case, once 5 server-sent-event sessions are created, other set/get operations cannot be performed.
I wonder if there is a way to avoid this situation (for example, the request to create the 5th server-sent-event session is not allowed by nginx..)
Please let me know if you have any idea. Thanks.
