After benchmarking resource usage and performance, I’ve come to the conclusion that SQLite is definitely the best way to go for Roundcube. Having trouble making the decision? This article may help clear things up for you.

Here are the pro’s for running Roundcube over SQLite:

* SQLite is generally faster than MySQL
* Since the SQLite databases are stored ...

Roundcube backups and logs can be found at the following directory on the cPanel-based server:

Code: Select all

ls -la /var/cpanel/roundcube

Simple way to list all the available backups in this directory is:

Code: Select all

find /var/cpanel/roundcube -maxdepth 1 -type f -name "roundcube.backup.sql*"

Via root SSH access, the following command may be used to monitor the Roundcube logs while sending a test message in attempt to trigger the issue (and to see the resulting error details that are logged):

Apparently the Out of the box CentOS kernel doesn't support reiserfs and a whole bunch of things. The support for ReiserFS will be built into the CentOS Plus kernel, but the centos plus for CentOS 5 isn't populated.

The CentOSPlus repository contains packages that are upgrades to the packages in the CentOS base + CentOS updates repositories. These packages are not part of the upstream distribution and extend CentOS's functionality at the expense of upstream ...

Here are the possibles solutions to it.

1) Confirm that session.save_path is set as /tmp in /usr/local/lib/php.ini

3) session.gc_maxlifetime is set as 14400

4) session.bug_compat_42 is turned off

5) If none of the above works, try the following.

touch /var/cpanel/usecpphp

cp -Rpf /usr/local/apache/modules/mod_bwlimited.so /usr/local/apache/modules/mod_bwlimited.so.bak


Now that we have the backups, it’s time to modify the mod_bwlimited.c file.

Go to the cpeasyapache source directory.

Code: Select all

cd /home/cpeasyapache/src


Open the mod_bwlimited.c using your favorite ...
