But inside cron, stdin is /dev/null (or an empty file); cron does allow you to specify one or more lines of input in a crontab entry, but in general the application is not supplied with any input.

You should redirect /dev/null to stdin for the zlogin so it doesn't get stuck trying to read. Jerry ___ zones-discuss mailing list zones-discuss@opensolaris.org

When I was first implementing Solaris 10 (before the first S10 kernel patch was released), I found similar behavior when running JASS via zlogin. When I caused JASS to dramatically reduce its output (to almost nothing) the problem went away. I don't know if this is related or not - lots has changed in the code since then. -- Mike Gerdts http://mgerdts.blogspot.com/ ___ zones-discuss mailing list zones-discuss@opensolaris.org
