Hi, A friend of mine is maintaining a mail server for a school and I am helpig her out. There are just 150-200 accounts and the machine is having 512 Mb RAM and 1Gb swap running Cent OS with processor being AMD Athlon. spamd and spamc pair is used with qmail as mailserver and processing done via .qmail files. spamd is started as, /usr/bin/spamd -m 10 -x -u spamd -H /home/spamd Sometimes when there is heavy load we get in logs, Cannot open bayes databases /var/bayes/bayes_* R/W: lock failed: File exists (Bayes works properly though). The load average always hovers around 20.0 and top shows spamd is culprit. Also, I have trained over 10,000 each of spam and ham and also use all sare rules yet many spams are passing thru' last few days.
Now 2 questions, what is that error for and what more can I do for spam? The teachers are sick of spam since last few days. With warm regards, -Payal
