I have made some other tests :

    - reactivate the line do_full_eval_tests
    - suppress everything except local.cf, init.pre, v310.pre anfd  
v312.pre
      from /etc/mail/spamassassin and comment all lines in this files.

Restarting MailScanner and commenting out one line at a time, I found  
that the problem is with

loadplugin Mail::SpamAssassin::Plugin::Razor2



When I test spamassassin, all is working fine :

# spamassassin -D < sample-nonspam.txt |& grep -i razor
[12725] dbg: config: read file /usr/local/share/spamassassin/ 
25_razor2.cf

but when the compile_now() function is called from the main  
MailScanner process, it doesn't finish and comsummes high CPU

# ps -ef | grep MailScanner
