files, OPEN_MAX (usually 64), which can be increased, and a per-process hard limit (usually 1024), which cannot be increased. Action You can control the soft limit from the shell.
Java Error Too Many Open Files
In the C shell, use the limit(1) command to increase the number of descriptors. In the Bourne or Korn shells, use the ulimit -n command to increase the number of file descriptors. If the window system refuses to start new applications because of this error, increase the open-file limit in your login shell before starting the window system.

too; ProblemDeterminationDocument; JCC was appserver app server Technote (troubleshooting) Problem(Abstract) This technote explains how to debug the "Too many open files" error message on Microsoft Windows, AIX, Linux and http://www.ibm.com/support/docview.wss?uid=swg21067352 Solaris operating systems. Symptom The following messages could be displayed when the process has exhausted the file handle limit: java.io.IOException: Too many open files [3/14/15 9:26:53:589 EDT] 14142136 prefs W Could not lock User prefs. Unix error code 24. New sockets/file descriptors can not be opened after the limit has been reached. Cause System configuration limitation. When the "Too Many Open Files" error message is written to the too many logs, it indicates that all available file handles for the process have been used (this includes sockets as well). In a majority of cases, this is the result of file handles being leaked by some part of the application. This technote explains how to collect output that identifies what file handles are in use at the time of the error condition. Resolving the problem Determine Ulimits On UNIX and too many open Linux operating systems, the ulimit for the number of file handles can be configured, and it is usually set too low by default. Increasing this ulimit to 8000 is usually sufficient for normal runtime, but this depends on your applications and your file/socket usage. Additionally, file descriptor leaks can still occur even with a high value. Display the current soft limit: ulimit -Sn Display the current hard limit: ulimit -Hn Or capture a Javacore, the limit will be listed in that file under the name NOFILE: kill -3 PID Please see the following document if you would like more information on where you can edit ulimits: Guidelines for setting ulimits (WebSphere Application Server) http://www.IBM.com/support/docview.wss?rs=180&uid=swg21469413 Operating Systems Windows By default, Windows does not ship with a tool to debug this type of problem. Instead Microsoft provides a tool that you can download called Process Explorer. This tool identifies the open handles/files associated with the Java™ process (but usually not sockets opened by the Winsock component) and determines which handles are still opened. These handles result in the "Too many open files" error message. To display the handles, click on the Gear Icon in the toolbar (or press CTRL+ H to toggle the handles view). The i
