it has been 2 weeks since I've upgraded my ZCS from 7.1.4 on Ubuntu 8.04 to 7.2.1 on Ubuntu 10.04, and now I am facing some strange problems. Although it seems ZCS is working fine all the time, it happened 3 or 4 times in last days that I've got "imapproxy" and/or "stats" among services DOWN (as seen via Admin WEB GUI), and when I looked it up via SSH, it says "zmnginxctl is not runing", for example:
Sometimes simply "zmnginxctl start" did the trick, but sometimes I need to issue "zmcontrol restart" to get it up and running.
zmnginxctl is not running
Now, the weird part:
I've took a walk through SERVER SETTINGS and I noticed, that my ZCS has checked these options:
- This server is a reverse proxy lookup target: YES
- Services --> Reverse proxy: YES
- IMAP and POP --> Enable clear text login: Checked and grayed out
I really do not remember ever before running "Reverse proxy"!?
Any idea where did it came from? Did I maybe press one YES too much during upgrade?
I have firewall also on this machine, and those 7*** proxy ports are NOT opened.
Should I open them, or rather get rid of proxy?
...and if it is safe to remove it by simply un-checking it under SERVICES (admin web gui), and select that "this server is NOT reverse proxy lookup target"?
