Suggested fix
Should be fixed in current rawhide rpm. Thanks, Florian La Roche |
From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: If QUEUE get set to "" in /etc/sysconfig/sendmail (haven't investigating the significance of this, but at least it happened on my system when migrating from 7.3), then invoking sm-slient completely hangs the machine when booting. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Set QUEUE="" in /etc/sysconfig/sendmail 2.Reboot 3.Wait forever Of course, replacing step to by "/etc/init.d/sendmail restart" is the preferred way of debugging this! Actual Results: Machine hangs Expected Results: Machine should not hang! Additional info: In /etc/rc.d/init.d/sendmail, the sm-client is started up like this: The problem seem to come from this line: daemon --check sm-client /usr/sbin/sendmail -L sm-msp-queue -Ac \ $([ -n "$QUEUE" ] && echo -q$QUEUE) Now, if QUEUE="", then there will not be a -q command line option. This means that sendmail has no option indicating that it should run as a deamon. Instead, it believes it should do its default "send mail" thing, writes the error "Recipient names must be specified" and starts waiting for stdin. There is a similar thing [i.e.$([ -n "$QUEUE" ] && echo -q$QUEUE] in starting sendmail proper a few lines earlier, but in this case it works because there is also a "-bd" option that indicates that daemon mode should be used. I have a patch that I will attach - not sure if it is the best or right way, but do have a look.
