Thank you very much for the quick response!

How can I do that resp. how do I check on that?
[quote user="liverpoolfcfan"]If you use the command line z-push-top.php to monitor the connections to the server, you should see the ping/sync get cancelled immediately after the save is made in the Web client. You can watch for when the phone issues the next request to the server.[/QUOTE]
Thanks a lot! That helped me to find out that I was still missing some php packages on my OpenSUSE system. After installing these, everything worked fine – I feel a bit silly.
[quote user="liverpoolfcfan"]That being said, I have just been troubleshooting some erratic behaviour with another user who has a zimbra 8 installation, and we finally figured out the problem was being caused by the new DoSFilter added as a security mechanism in zimbra 8. When the z-push server was making multiple requests of the zimbra server in a short space of time, the zimbra server was treating it as suspicious behaviour, and throwing back a "Error 503 Service Unavailable" error. Whitelisting the IP address of the z-push server solved that problem. For reference, see: DoSFilter

Well, thanks for the hint, I added the ip of my z-push server to the whitelist. I think it would be nice to add this to the readme file.
One more question: I tried to do the same on a shared hosting site, which seems to be a bit tricky due to Alias directives, php packages, and other restraints. Could you provide any advice, e.g., link, on how to do that?
