File descriptors for pipes are leaking when executing some TMSH commands through scriptd.


iCall scripts cease to function, and scriptd must be restarted. Eventually the system logs error messages similar to the following: err scriptd[11946]: 014f0013:3: Script (/Common) generated this Tcl error: script did not successfully complete: the pipe system call failed, Too many open files.


TMSH commands must execute via scriptd (for example, running tmsh::modify in an iCall, but there may be other conditions that lead to the leak).



Fix Information

All pipes are closed when a TMSH command is completed, so file descriptors no longer leak when running some TMSH commands through scriptd.
