"subprocess exited with an error" warning

[kiti]

Hi, i can see always this strange warning in
/usr/local/cpanel/logs/error_log

when starting easyapache update on 2 different servers.

[2016-05-05 08:49:08 +0200] warn [cpsrvd] The subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/easyapache.pl) exited with an error: The subprocess reported error number 1 when it ended. at /usr/local/cpanel/Cpanel/Server/Handlers/SubProcess.pm line 155.

Hello,

Please post the output from the following command if the issue continues, so we can determine which version of cPanel is installed on your system:

cat /usr/local/cpanel/version

Thank you.

I'm seeing this error too. Everything still seems to be working as normal.

cat /usr/local/cpanel/version

Do you notice any additional output to /var/log/messages when this happens? Are any third-party applications such as Nginx or LiteSpeed installed on the system?

Thank you.

 

[Recifier]

There's no other output to /var/log/messages at the time of those errors and there are no 3rd party applications for http installed.

I've seen the error on servers running Centos 5.11 x86 and Centos 6.8 x86_64. Both have the same EA config and both displayed the same error.

The log for the EA build shows that the errors were output right at the beginning of the build:
Top of EA build log:

If the browser window is closed or stopped the build will continue in the background.
The build output should start shortly...

[cPanelMichael]

It's possible this stems from a lack of available memory on the system. Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

Thank you.

 

[Recifier]

Ticket is 7593969.

I just started a new EA3 build and saw the error again. There's about 6G of ram free at the moment, so wouldn't expect it's memory related (plus this particular system has no users at the moment).

 

[cPanelMichael]

Hello,

To update, internal case CPANEL-7394 is open to address reports of cpsrvd errors in /usr/local/cpanel/logs/error_log when using EasyApache 3 UI in WHM. The error output will generally start like this:

warn [cpsrvd] The subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/easyapache.pl) exited with an error: The subprocess reported error number 1 when it ended. at /usr/local/cpanel/Cpanel/Server/Handlers/SubProcess.pm line 155.

I'll update this thread once a resolution for this case is released. In the meantime, it's safe to ignore these warning messages as I've not seen any reports of it resulting in actual problems with functionality.

Thank you.
