Has anyone else run into a problem with Emacs locking up while editing
Perl scripts?

I'm running Perl 5.005_02 and GNU Emacs 20.2.3 under Solaris OS 5.6
using the cperl-mode commands shown below in my .emacs file.

Emacs is locking up intermittently while I edit various Perl scripts.
It's unpredictable and I can't repeat the problem (although it happens
frequently).  It does stop when I remove the cperl-mode code.

Does anyone have any ideas on what's causing it or how I can try and
determine what's causing it?  Thank you.
