What can I do if I am unable to start the qmail service in Plesk?
First of all, make sure that qmail is not running.
If so, try to start it from the command line.
If that does not work take a look at the /usr/local/psa/var/log/maillog logfile for helpful error messages.

When the cron file /etc/cron.daily/1hup_apache_logs is executed the httpd service is not able to reload properly and it get stuck. The service is dead and it needs to be restarted manually. Even the server load goes high. And in some cases the server even crashes.
To Resolve this issue.
Change “reload” to “restart” in /etc/cron.daily/1hup_apache_logs
Content of /etc/cron.daily/1hup_apache_logs are as follows:
#!/bin/bash
#/etc/rc.d/init.d/httpd_app_init reload-grc
# XXX Fix of the “lost child came home” issue
! /sbin/chkconfig httpd || /etc/rc.d/init.d/httpd_app_init reload

#!/bin/bash
#/etc/rc.d/init.d/httpd_app_init reload-grc
# XXX Fix of the “lost child came home” issue
! /sbin/chkconfig httpd || /etc/rc.d/init.d/httpd_app_init restart
