OK, I tried this method from the command line on my Ubuntu 6.06 LTS install, and when I used the
method, although zmcontrol status showed all the modules running, the web UI shows red "X" by Spell, SNMP, MTA, and Antivirus as well as Status. Just going from root to su - zimbra and then running zmcontrol stop & start, and the only red X is by Status. I don't know why, or even where to look to find out why, but if I had to guess I wonder whether running the whole command from root results in some odd file permissions issues.su - zimbra -c "zmcontrol start"
I'll be interested to hear how it works (or not) for SSS. . .by the way, you didn't say what version you were on. I presume "yum" means SuSe, but what release of Zimbra?
Whatever is going on, although I've had that red X by Status for a couple of weeks (despite stopping & restarting using the shell script backup every night), I am unable to tell that it hurts anything. The graphs and the nightly summary emails are clearly generated by other processes.
