            Bug ID: 358751
           Summary: konsole loses file descriptors and eventually runs out
                    of them and crashes
           Product: konsole
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kuenne at rentec.com

If I start a fresh konsole process it has 3 socket connections open. If I work
for a while and then check again the number of sockets belonging to konsole
increases. This is going on until konsole reaches the file descriptor limit and
either won't let me open more sessions or crashes. Most of the socket
connections are between itself. Following is the current situation on my
desktop for instance (netstat_unix is a simple script which adds the other end
of a socket to the output):

./netstat_unix | grep konsole

Over time the number of sockets from konsole process 25237 to itself will
continue to rise.
This is with Version 15.12.0, Using: 
KDE Frameworks 5.16.0
Qt 5.5.1 (built against 5.5.0)
