Hello,

I am using the Horde Framework version 4.0.6, and set up Xcache as the  
caching backend. I found out my Horde logs were being spammed by the  
following messages:

These messages occured only when running one of Horde's CLI scripts in  
/usr/bin. Caching via the web server seems to work fine. It turned out  
that Xcache doesn't support PHP CLI, and won't do in the future. This  
seems to generate these notices.
http://xcache.lighttpd.net/ticket/228

When I disable the Xcache backend in Horde, PHP CLI scripts like  
horde-alarms run just fine without logfile spamming.

I tried a workaround by disabling Xcache in php.ini for the CLI, but  
that generates just another obvious error:
---
PHP Fatal error:  Call to undefined function xcache_set() in  
/usr/share/php/Horde/Cache/Storage/Xcache.php on line 51
---

The solution would propably for Horde be to disable Xcache when it is  
being called from the CLI.

Thank you,
Stan Hisken
