           Summary: konqueror + konsole + kate are spamming with open FDs
                    (FileDescriptors) whenever they fork(+exec other
                    programs).
           Product: konsole
           Version: 1.3
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: coeus gmx de


Version:           1.3 (using KDE KDE 3.2.0)
Installed from:    Gentoo Packages
Compiler:          gcc 3.2.3 gcc (GCC) 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r3, propolice)
OS:          Linux

konsole causes kde to crash after opening >50 or >60 commandtabs (Befehlsfenster in german).
each new session has 3 new opened FDs.

it seems that the programmer has forgotten to set several close-on-exec flags.

at least konqueror(->run_command) and kate('s terminal) are doing the same, so there may be an other program/library/deamon that causes this.
