Exceeded time limit Plugin::Check::_rawbody_tests_0

[fchan]

Hello,
I noticed recently (within the past two months) I'm getting this 
error message from spamassassin. Here is line from the maillog:

Jan  5 15:07:40 s1 spamd[21160]: check: exceeded time limit in 
Mail::SpamAssassin::Plugin::Check::_rawbody_tests_0, skipping further 
tests

I have set spamd --timeout-child=300 so should I raise it to about 
600  but will there be consequences like spammer overloading the 
server to lockup all spamd processes or other problems this can cause.

Thank you,
Frank Chan
