Solved Internal Server Error 500 No response from subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/addon_dotDefender.cgi): The subprocess exited with statu s 2 (ENOENT).

After a recent installation of dotDefender, the following error came up:
“Internal Server Error

500

No response from subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/addon_dotDefender.cgi): The subprocess exited with statu s 2 (ENOENT).”

The log file for dotDefender, /usr/local/APPCure-full/log/dotDefender_bpd.log, gives further detail:

The fix was to install Crypt::Passwd::XS as such:

/scripts/perlinstaller Crypt::Passwd::XS

Update 1-29-2016

This error popped up again, and seemingly coincided to an upgrade in cPanel.  The upgraded version is WHM 54.0 (build 8).  The error was almost identical to the one above, but instead of outputting the error to the dotDefender log, it was going to the cPanel log (/usr/local/cpanel/logs/error_log) as such:

Speaking with cPanel support,

This should be fixed. After further review we didn’t acutally rename all of these packages, it looks to maybe only be some API calls rather than the package. This was failing because the following file was modified.

[21:37:25 cp root@7449479 ~]cPs# head /usr/local/cpanel/Cpanel/Accounting.pm

ypackage cPanel::Accounting;

It should have been this looking at another server.

[21:40:42 cp root@7449479 ~]cPs# head Accounting.pm package Cpanel::Accounting;

Once I corrected that I could load the page. I did have a token error and had to login and then got an access error but I believe as root you should have no issue now.

The updated file correcting the issue is below:

#!/usr/local/APPCure/bin/PERL
#WHMADDON:dotDefender:Applicure dotDefender

use lib '/usr/local/cpanel';
#use lib '//usr/local/cpanel/3rdparty/perl/514/lib64/perl5/cpanel_lib';

use Cpanel::CheckPass              ();

my $cphulk = Cpanel::Hulk->new;

my $my_domain = Cpanel::AcctUtils::getdomain($ENV{'REMOTE_USER'});
