--- Begin Message ---Package: nis Version: 3.16-2 Severity: normal Tags: patch When our NIS server becomes unavailable, all of our NIS clients die a few minutes later. I strace()d one on a deliberate outage and found that it died with SIGPIPE. Here's an extract from the strace output and a suggestion for a patch. Other programs in the nis package seem to ignore SIGPIPE (in different ways).
