or

  "java.net.SocketException: Broken pipe"

Resolution

The error

   Exception caught. Message is: Exception writing to response output stream : org.apache.catalina.connector.ClientAbortException java.net.SocketException: Broken pipe

is a result of one of these circumstances:   

• The backend server is Responding to the request too long, the SPS gave up;
• The backend server responded with something the SPS did not understand;
• The end-user actually cancelled the request closing the browser;
• A network error occurred between the SPS and backend server.

Investigate the behavior of the backend server and also investigate the network (including load balancer and firewall) when the issue happens.

Tune also the CA Access Gateway (SPS) for the following server.conf parameters:

• http_connection_pool_min_size
• http_connection_pool_max_size
• http_connection_pool_incremental_factor

if the CA Access Gateway (SPS) lacks of connection.
