Fixing Common Perl Issues – cPanel

Sometimes you’ll notice that a certain function of cPanel or WHM was working fine, now all of a sudden you’re getting results that you’ve never seen before. Believe it or not, many problems with cPanel functionality related to processes running off of scripts is because of a perl corruption. To resolve this, usually the first step you should take is running a cPanel update, as this will correct most issues. If the problem persists, you may need to recompile perl from it’s core.

Before we start, here are a few of the most common indicators that there is a perl issue on your server:

  • Accounts are not created properly, like missing files
  • Frontpage extensions refuse to be installed
  • Stats won’t run, result in cryptic perl errors
  • Error messages that look like this:
(internal death) Sat Jun 3 21:01:55 2006 [32719] error: List::Util object version 1.14 does not match
 bootstrap parameter 1.18 at /usr/lib/perl5/5.8.7/i686-linux/ line 92.
==> Starting cpbandwd (bandwidth monitoring for IMAP/POP)
Can't locate Class/ in @INC (@INC contains: /usr/local/cpanel /usr/lib/perl5/5.8.7/i686-linux
BEGIN failed--compilation aborted at /usr/lib/perl5/site_perl/5.8.7/Unix/ line 8.
Compilation failed in require at /usr/local/cpanel/bin/cpbandwd line 15.
BEGIN failed--compilation aborted at /usr/local/cpanel/bin/cpbandwd line 15.

In some cases, the error is specific about a perl module missing. If this is the case, look for the perlmod format in the error message. In the above example you can see ‘List::Util’ being referenced, so you can try to reinstall that either manually or from WHM:

/scripts/perlinstaller –force List::Util

If reinstalling the perl module itself does not solve the problem, you can recompile perl. First, do a perl -v from command line to see what version you are running. Then follow these steps:

tar xvzf perl587installer.tar.gz
cd perl587installer


If you are running 5.8.8, use the installer from:

The recompile may take as long as 20 minutes to complete.

  1. Thanks for this info. Had to resort to reinstalling Perl as outlined above. But it’s certainly not 20 minutes. 2 and a half hours later, and it’s still going.
