Cause:
The error "java.net.SocketException: Too many open files" indicates that the limit on the number of "Open files", which is 1024 by default, has been exceeded. This is an operating system issue. Increase the max open files parameter to a larger value for the user running the Spotfire Server process by adding the following two lines in the /etc/security/limits.conf file. Then, restart the Spotfire Server.
