(Not all processes could be identified, non-owned process info For example, to verify the status of the sockets opened for a single process, you can execute the following command: $ netstat -tulpn | grep 7790 This can be verified with the netstat command. Besides it, you should also check what are actually doing your sockets. So, right now you have the count of open handles on your machine. On the other hand, if you want to have the list of handles per user, you can run lsof with the -u parameter: $ lsof -u jboss | wc -l BufferedReader is a resource that must be closed after the program is finished with it: static String readFromFile(String path) throws IOException ' | sort | uniq -c | sort -n

It uses an instance of BufferedReader to read data from the file. The following example reads the first line from a file. Any object that implements, which includes all objects which implement java.io.Closeable, can be used as a resource. The try-with-resources statement ensures that each resource is closed at the end of the statement. A resource is an object that must be closed after the program is finished with it. The try-with-resources statement is a try statement that declares one or more resources. Are you using resources (Sockets/IO Streams/Database connections) without closing properly the connection?Ī common way to release safely resources is to use the try-with-resources statement. You can approach this issue with the following checklist: 1) Check what your application is doing. In Linux, the maximum open file limits are set by default for each process or user and the defaut values are quite small.Īlso note that socket connections are treated like files and they use file descriptor, which is a limited resource. The error Java IOException “Too many open files” can happen on high-load servers and it means that a process has opened too many files (file descriptors) and cannot open new ones.
