I suggest the following small fix with the following reasoning:
amtReadin functionLinuxProcessList_readCmdlineFileare meant to protect the execution of the for loop (and what follows it), which is not supposed to be run withamtRead == 0(if I understand correctly),LinuxProcessList_recurseProcTreeat line 883 after the "offending" call toLinuxProcessList_readCmdlineFileat line 856.To me this is a quick fix and the setting of command name of processes seems a little bit clumsy (i.e.
readCmdlineFileis not just reading, but actually setting the command name of a process and classifying it as a kernel thread), however, I lack the insight as well as experience to write it better. Maybe setting the command name of a zombie process should also be moved toreadCmdlineFileand the function renamed. Please, let me know what you think about it.This closes issue #930.
