From: Michal Privoznik <mprivozn@redhat.com> The aim of virProcessAbort() is to reap a child process. It does so by waitpid()-ing and possibly sending SIGTERM/SIGKILL to the child process (and waitpid()-ing again). Nevertheless, if everything fails a debug message is printed. But the message mentions only the PID and not errno (set by previous waitpid()) which may be useful. For instance when virProcessAbort() is called over a PID that's not our child: failed to reap child 16325, abandoning it: No child processes Signed-off-by: Michal Privoznik <mprivozn@redhat.com> --- src/util/virprocess.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/util/virprocess.c b/src/util/virprocess.c index 3889ba90f9..e8120c1bdc 100644 --- a/src/util/virprocess.c +++ b/src/util/virprocess.c @@ -168,7 +168,8 @@ virProcessAbort(pid_t pid) } } } - VIR_DEBUG("failed to reap child %lld, abandoning it", (long long) pid); + VIR_DEBUG("failed to reap child %lld, abandoning it: %s", + (long long) pid, g_strerror(errno)); cleanup: errno = saved_errno; -- 2.49.1
