Abstract
A method, system and computer program product for caching socket connections while ensuring that there are file descriptors available for the applications. File descriptor references and their referenced objects are stored in a predefined memory region of the heap (“file descriptor heap”). Each time a socket connection is cached, a file descriptor reference may be created to be associated with the socket connection's file descriptor, where the file descriptor reference references the object of the cached socket connection. In order to ensure that there are available file descriptors for the applications, the file descriptor references and their referenced objects are collected by the garbage collector in response to various events (e.g., too many file descriptors are open) thereby freeing the file descriptors that were previously associated with the collected connection objects to be used by the applications.
