[Bug 1838109] Re: civetweb does not allow tuning of maximum socket connections

[James Page]

** Description changed:

- Civetweb does not offer an option for configuring the maximum number of
- sockets available. Some users run out of sockets and are left with no
- workaround.
+ [Impact]
+ RADOS gateway can run out of sockets prior to consuming the CPU and memory resources on the server on which it is running.
+ 
+ [Test Case]
+ Deploy RGW to a large server; scale test - RGW processes will only be able to service around 100 open connections.
+ 
+ [Regression Potential]
+ Medium; the fix introduces a new configuration option for civetweb (the web connector for RGW) to allow the max connections to be set via configuration, rather than being set during compilation; improvement has been accepted upstream in the civetweb project.
+ 
+ [Original Bug Report]
+ Civetweb does not offer an option for configuring the maximum number of sockets available. Some users run out of sockets and are left with no workaround.
  
  This patch adds a new user-configurable parameter, "so_max_connections".
