I'm seeing the following code in do_execve() frequently being
triggered when scripts are executed on my SMP machine under load:
if (imgp->vmspace_destroyed) {
/* sorry, no more process anymore. exit gracefully */
#ifdef MAC
mac_execve_exit(imgp);
if (interplabel != NULL)
mac_vnode_label_free(interplabel);
#endif
exit1(td, W_EXITCODE(0, SIGABRT));
/* NOT REACHED */
error = 0;
}
Needless to say, the scripts get pretty unhappy when they're summarily
aborted. What is the cause of this?
Kris
