Description
Posted by: Date: 12:14 AM 12-18-2005 Boinc CC V 5.2.6 - 5.2.13 passes its open file descriptors on to the applications when the applications are started. This includes open network sockets and connections.
Proposed fix: Close all excess file descriptors after fork, before exec loads the application.
Posted by: Date: 1:54 AM 12-18-2005 set close-on-exec flag for descriptors in boinc_socket() and boinc_fopen(); hopefully this gets them all.
Posted by: Date: 12:26 AM 05-06-2006 This bug is still present in Boinc CC 5.4.9 See the attached output of lsof for the simap applikation. The application holds a descriptor to the socket for remote gui rpc and one for the aktive connection from BoincView? to the CC.

All sockets are set to close-on-exec now (unix).
