This looks more like the absence of SIGPIPE than an inappropriate SIGPIPE. I can reproduce both of those error messages by running the commands with SIGPIPE ignored. grep(1) seems to behave strangely on write errors, not aborting, for example yes | { trap '' PIPE; grep -v foo; echo $? >&2; } | : prints an endless stream of error messages. Note that sh(1) silently ignores attempts to change the disposition of signals that were ignored on entry to the shell, so a trap - PIPE is unlikely to help you. Similarly, SIGPIPE may be blocked (masked). Few programs expect this. The -i and -j options in procstat should be helpful in finding what exactly is wrong with SIGPIPE. (These options are relatively new, but should be in 8.1.) -- Jilles Tjoelker _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
