Default z-push + zimbra Session Id changed - OLD [XX] -> NEW [XX]
Hi,
I have a strange problem with the change of sessions, when I'm sending email from my android 2.3.3 (SGS+) and at the same time I'm logged in to Zimbra webmail:
My configuration below:

Centos 5.6
z-push-1.5.5-790
zimbraBackend51.4
PHP version: 5.3.8
Zimbra Release 6.0.14_GA_2928.RHEL5_64_20110802123437 CentOS5_64 FOSS edition

Everything is working correctly: I can sync my mails, calendars, contacts, et.
The problem is, when I send mails from a mobile, I noticed "session id changed" in debug.txt quite often:

...
and so on...

At the same time I noticed this in mailbox.log from zimbra server:

...........

(10.0.0.3 is the internal Apache server where z-push is installed and it is separate server.)

There would be nothing wrong with that, because I have full functionality, but problem arises when I'm logged in to Zimbra web and my phone is connected to zpush on the same account at the same time, then I "feel" double SOAP requests in browser: clicking on one of the mail execute another requests (my mouse pointer is busy "twice" , not once as before). Finally, my zimbra webmail jumps me to the first thread/mail in my Inbox. It's a bit tedious.

Has anyone encountered a similar problem?
The temporary fix is to restart httpd on the z-push server, but after a while the problem occurs again.
When I'm using 5 minutes interval for syncing (not push), there is no problem.
Please help.

I replied to your post on the z-push forum ... but here you have more debug information to work with.


11/09/11 19:39:40 [29938] [l@domain.com] Session Id changed - OLD [15936] -> NEW [15942]
...
11/09/11 19:39:41 [29943] [l@domain.com] Session Id changed - OLD [15937] -> NEW [15943]
...

11/09/11 19:39:45 [29938] [l@domain.com] Session Id changed - OLD [15942] -> NEW [15948]

Here you are showing that there are 6 separate ping processes running on your phone.

You need to figure out why your phone is losing connections to the server.

Are you using wi-fi that turns off when the screen goes off ? That would cause it to lose a connections

Or do you see any sessions that just die - all should start with a logon and end with a logoff. Are you seeing any end abruptly ? You could have a corrupted meeting/message that is breaking the sync.
