[horde] ActiveSync Client(s) overload server

[Steffen]

Hi,

last days the partition of the SQLDB of Horde run full, I cleared the 
problem and restarted the server. Since then ActiveSync clients have 
problems to sync.

Five clients open more and more connections running with 100% CPU each, so 
that within half an hour the load of the server increases so high, that 
it is infact a denial-of-service. I have blocked them now.

Is there a way to limit active connections per client within Horde? If I 
limit the access to the GUI on the firewall, people find the GUI unusable.

Other clients cannot sync as well, but do not consume noticable CPU time 
in that way.

Before I ask about the sync problem itself, I'll update the Horde 
installation to the latest PEAR packages, maybe something was fixed.
However, to have several ActiveSync clients take the server down is 
troublesome.

Kind regards,
