Hi,

for me : upgrade on a debian test server from 3.6.8 to the deb package
3.9.1~rc1+git20100826-1

Yes, there is also the system.log to logrotate, but now the
dspam_maintenance script cleans it.

Same, floating point after. and cssstat doesn't work anymore :
# cssstat user.css 
filename user.css length 1573112
extent 0: record length 98317
Segmentation fault

For the maintenance, I use dspam_maintenance for my test server but I
won't use it (nor dspam > 3.6.8) on a prod server until hash driver is
broken.

I don't know if there is a "normal css db size". I found a 300M db and
a 3M, same configuration, same n° of emails/day but 300M is badly
trained and 3M is carefully trained.
