I use it. 'imap_cache'='memcache' enables memcache for part of imap-related cache. 'session_storage'='memcache' enables memcache for session storage. And configuration of memcache location: 'memcache_hosts'=array( 'localhost:11211', '192.168.1.12:11211' );

.. I use the same and get this error.



[30-Sep-2011 14:59:02 +0200]: DB Error: Memcache failure on host localhost:11211 in /dominios/pk25.com/www/intranet/roundcubemail-0.6/program/include/rcmail.php on line 370 (POST /intranet/roundcubemail/?_task=login&_action=login)

But I have the memcache config

pk25.com:/dominios/pk25.com/www/intranet/roundcubemail/logs# telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.

There is a problem with specific versions of memcached and the php-memcache module as can be read here. This is the logging of memcached when logging into roundcube:

-----
<36 new auto-negotiating client connection
36: Client using the ascii protocol
<36 incr __CONNECTIONTEST__ 1
>36 NOT_FOUND
<36 get gi59ib235ih5n87rrf6v4jk955
>36 END
<36 delete gi59ib235ih5n87rrf6v4jk955 1
>36 CLIENT_ERROR bad command line format.  Usage: delete [noreply]
<36 connection closed.
-----

I tried to install a correct version according to this page (I have memcached 1.4.5 and installed php-memcache 2.2.5) but this doesn't work either. I can't seem to find the code that deletes a specific key (I am not a PHP programmer). This code probably adds a TTL of 1 to the delete somehow. I want to remove this, or set the TTL to 0 which should also work. If someone has some insight about this, please let me know. This is driving me crazy.

Hi!

First of all this is a really great feature. Respect!


But i have noticed if the memcached is busy or hangs the roundcube fails at all!

Dear RC-Team, please think about of a fall-back option!
This would make the life a little bit easier in the 19" rack...
Thanks.


Rgds.

I solve this using:

apt-get install memcachedb

and change the config to..

$rcmail_config['memcache_hosts'] = array( 'localhost:21201');

Hi!

Nice to hear you got it running.
But i don't get the deeper sense of your post...

I had this problem too. I dug around and this is apparently due to a change in the memcached protocol on servers >=1.3.0. I installed the beta version 3.0.6 of the memcache PHP extension and it fixes the delete command error, which then allows RoundCube to work.
