Webmail not loading properly

[Delton]

We moved all sites from server A to server B, and in server B now no webmail client (horde, roundcube and squirrel) is openning the messages. All web sites have the same issue, the clients not have more access to webmail.... The system try to load something but stay loading without load the messages, or even open corectly.

I find the solution in other forum post:

Try disabling the "PHP-FPM service for cPanel Daemons" You can do that from WHM / Service Manager.

then restart apache and try again, probably will fix your problem.

Hello @Delton,

It's possible this relates to an existing internal case (CPANEL-11106) where cPanel PHP-FPM hits the open files limit. Could you run the command below and let us know the output?

grep "Too many open files" /usr/local/cpanel/logs/php-fpm/error.log

Thank you.

Hello,

Internal case CPANEL-11156 updates the internal PHP version used with cPanel to 5.6.30 and should address the problem reported on this thread. It's included with cPanel version 62.0.12:

Fixed case CPANEL-11156: Update cpanel-php56 to 5.6.30-1.cp1158.

This version is currently published to the EDGE build tier. More information on how new builds are published is available on our cPanel & WHM Product Versions and the Release Process documentation.

Thank you.

 

[manokiss]

Im on 62.0.15 and this problem persist. I had to disable "PHP-FPM service for cPanel Daemons" to had it working.

 

[hseagle2015]

Hi,

I can confirm that we have the same problem on cPanel servers running version 62.0.16.

/scripts/restartsrv_cpanel_php_fpm fixes the problem, but only temporarily.

 

[cPanelMichael]

Hello,

Please confirm if the information on the following post helps:

cpanel_php_fpm down

Thank you.
