    • Type: Bug
    • Resolution: Fixed
    • Priority: Critical
    • Component/s: core
    • Environment:
      Jenkins 1.472 on RHEL 5 x86_64

      Trying to navigate to Jenkins web site, browser keeps loading and loading. When checked on Jenkins console it showed that Jenkins failed with the following:

      Jul 6, 2012 1:49:28 PM winstone.Logger logInternal
SEVERE: Error during HTTP listener init or shutdown
java.net.SocketException: Too many open files
        at java.net.PlainSocketImpl.socketAccept(Native Method)
        at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:408)
        at java.net.ServerSocket.implAccept(ServerSocket.java:462)
        at java.net.ServerSocket.accept(ServerSocket.java:430)
        at winstone.HttpListener.run(HttpListener.java:136)
        at java.lang.Thread.run(Thread.java:662)

      I have verified open files and it seems that unreasonable large number of descriptors is open to various jar files, with jenkins-core being the leader:

      $ ls -la /proc/26867/fd | grep jar | wc -l
      876
      $ ls -la /proc/26867/fd | grep jenkins-core | wc -l
      462
      $ ls -la /proc/26867/fd | grep stapler | wc -l
      173
