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.

<username> hard nofile 40000

Example: If Spotfire is running under "root" user:
--------------
root soft nofile 40000
root hard nofile 40000
--------------
Note: An issue exists for a high number of open files under Red Hat 6. (Refer to https://access.redhat.com/solutions/33993). Consult with your Administrator before making any changes as the change outlined above will modify the parameter for the root user.
