Sujet : z-push has stopped working


Until a few weeks ago (I haven't really had time to look into this) I used 
Mail for Exchange to synch the contacts and calendar on my Nokia N900 to Kolab 
(version 2.3.4).

Suddenly this stopped working. As far as I can tell, I haven't made any 
relevant changes, either to Kolab or to my phone. Obviously, something has 
changed, but I haven't got a clue.

The apache error log shows this (last line, full log attached):

[Fri Dec 02 18:00:40 2011] [error] [client] PHP Fatal error:  
Allowed memory size of 268435456 bytes exhausted (tried to allocate 
-2147482625 bytes) in /kolab/var/kolab/www/z-push/backend/kolab.php on line 

I also activated debugging on z-push (debug.txt attached). I get this:

12/02/11 18:15:46 [30162] [paul] Unknown:0 Unknown: SECURITY PROBLEM: insecure 
server advertised AUTH=PLAIN (errflg=1) (8)

So php is complaining about memory, and z-push tells me I have a security 
problem. I tried increasing memory_limit to 256MB in php.ini, but that didn't 

Any ideas what this may be? If this insecure server problem is for real, what 
do I need to do to fix it?
