This problem is caused when a high number of concurrent users get a connection to the Sametime Advanced server. Java™ opens many files and Sametime Advanced uses a lot of file descriptors. Eventually, the server runs out of file descriptors. You can fix this by editing the file descriptor limit in the limits configuration file in Linux.
