Upcoming Roundcube Performance Enhancement

[cPanelDavidG]

We have noticed many threads about issues regarding excessive CPU utilization by Roundcube. We have recently located the cause of this issue and are performing some final testing on a resolution to this issue. This resolution already published in our BETA build. Once this modification is found to meet our quality standards for EDGE, we will be pushing this to our EDGE build (11.25).

We understand the majority of you are using version 11.24. Please understand we intend to backport this enhancement to 11.24 in the near future. We do not have any exact ETAs on the propagation of this enhancement. However, this thread will be updated when more information becomes available.

To ensure all Roundcube users benefit from this enhancement, we are sharing our findings with the developers of Roundcube once we have completed the testing and rollout.

If you have any questions, desire any clarification, or have any feedback please post to this thread. Your feedback helps us to better meet your needs.

David - thanks - that is absolutely awesome.
I also love that your team is going to go the extra mile and share the enhancement with the Round Cube folks

Another reason to stick w/ cPanel. :-)

What's the status on this? I just had roundcube bring a server to its knees (load 174) with a truckload of roundcube processes.

I issued pkill -u cpanelroundcube and then restarted cPanel services just to be sure.

Top Gov's discussing global warming trying to find away out and this issue is ongoing?

Imagine the co2 generated by the extra cpu load generated by this bug.


I found a thread it people reporting this problem since way-back and this is still unsolved....

The aforementioned issue in Roundcube is fully resolved. I would consider upgrading to the latest CURRENT build or wait for the upcoming RELEASE build of cPanel version 11.25.

Please refer to the earlier reply in this thread linking to the cPanel 11.25 release page and release notes.

I upgraded to 11.25 but cpanelro still has a high CPU load.
This only happens on one of my servers.

Thanks,

This is a bad joke, after waiting that 11.25 release came out, this didn't fix the roundcube error, server did the update very early this morning (about 3:00 am CST) and a few minutes ago:

/var/cpanel/3rdparty/bin/php -c /usr/local/cpanel/3rdparty/etc/roundcube /usr/local/cpanel/base/3rdparty/roundcube/index.php

What is the full cPanel version number? The following command may be used to obtain the version information:

# cat /usr/local/cpanel/version && echo

Has the system Roundcube configuration been converted from MySQL to SQLite? Via root SSH access the following command may be used to determine the status of Roundcube using SQLite or MySQL:

# grep roundcube_db /var/cpanel/cpanel.config

If the system Roundcube configuration is still using MySQL I would consider converting it to SQLite as detailed in the cPanel 11.25 Release Notes (available for download in PDF format): cPanel Release Notes - Version 11.25

What is the exact error you are referring to? Please also see my last reply regarding Roundcube performance and optional conversion to SQLite as mentioned in the cPanel 11.25 Release Notes.

Just out of curiosity, what sort of performance gains would you expect to see converting to SQLite ?

Roundcube is always hogging resources on a number of our servers, would this help it to calm down?

Cheers.
