      Use the admin api to deploy/undeploy a large number of times, for example in adminshell

      for (i = 0; i < 300; i++)

      { deployVDB("foo.vdb"); undeployVDB("foo", 1); }

      There will be well over 300 new open sockets at the end of the run. Prior to the previous commit on this issue in 7.4, at most 64 of them can be buffer files that will get auto cleaned up, but the rest of them will be remoting serversockets that do not seem to be limited by the suggestion in JBAS-6665.

      VDB deployments through the AdminApi caused the application server to leak server sockets and listening threads, which could cause failures due to too many file handles being opened. A patch has been applied to fix this issue. As a result, server sockets and listening threads are no longer leaked so users will no longer encounter these failures.
