I've got Centos 6.5(6 now) ala perfect server and have been using roundcube 1.0 for quite some time happily.... but I've noticed today for about an hour or so I was getting 'connection to storage server failed' and then suddenly it started working again. I dont see anything in the mail logs and am trying to find out where roundcube puts its log. its under /var/www/apps/ folder. any ideas? really weird! cdb.
