I have a Java program that executes
Runtime.getRuntime().exec("ls -l");
many times, once for each directory in the system.
My test system has more than 1,000 directories and Runtime.getRuntime().exec("ls -l"); seems to error out after 480 directories or so.
The error message I'm getting is is "Error running exec(). Command: [ls, -l] Working Directory: null Environment: null".
I'm guessing it's running out of some required system resources or is it?
Is there any way to process all directories without erroring out?
Relative comment from an answer:
I should clarify that I was using Android SDK's adb.exe. I wanted to
execute something like Runtime.getRuntime().exec("adb shell ls -l")
multiple times on different directories.

You should explicitly close the input/output streams when using
Runtime.getRuntime().exec
.
