I thought I made a comment about this earlier, but apparently I didn't send it out or it wasn't recorded: Symptom: The issue is caused by tar in the PUSHOUT macro in add/extract.c as identified below, during the extract. If and when the tar stuff is replaced with libarchive, this issue will fail sooner (and this should be done because this would save a lot of time and resources when extracting large packages like openoffice): #define PUSHOUT(todir) /* push out string */ \ if (where_count > (int)sizeof(STARTSTRING)-1) { \ strcat(where_args, "|/usr/bin/tar --unlink -xpPf - -C "); \ strcat(where_args, todir); \ if (system(where_args)) { \ /*** XXX: FAILS HERE ***/ cleanup(0); \ errx(2, "%s: can not invoke %ld byte tar pipeline: %s", \ __func__, (long)strlen(where_args), where_args); \ } \ Real problem: The actual problem is that the master and slave pkg_add processes aren't communicating properly with one another, s.t. the slave instances aren't breaking the master execution at the first sign of failure.
