> 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?

> 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
