Timeout problems

[Rice, Kevin]

I'm using v0.1.2 of spamass-milter with SA 2.4.1/sendmail 8.12.6 on Debian 
woody and seeing messages similar to the following in my logs:

Could there be something I've got set incorrectly that's causing the timeout. 
The source and destination servers that are passing that message are both 
internal. I currently have spamd running as root, sendmail's QUEUE_INTERVAL is 
set to 10 minutes, and I've got the milter entry in the mc file which generated 
a new cf file set to the default in the docs as listed below:

INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/sendmail/spamass.sock, F=, 
T=C:15m;S:4m;R:4m;E:10m') 

I've got spamd running with just the default -c that the Debian package lists. 
My local.cf consists of the following:

required_hits 4.00
subject_tag SPAM:
whitelist_from  address@hidden
whitelist_from  address@hidden
whitelist_from  address@hidden
whitelist_from  address@hidden
report_header   1
use_terse_report        1
defang_mime     0

Is there anything I should change? This is running on a P-II 233MHz with 128M.
