I am having a problem where my whole computer grinds to a halt during the Bayes database reorganization process sometimes. I'm running SpamAssassin 2.55 on Linux Mandrake 8.1 on a 1.5 GHz Pentium machine with 512 MB of RAM and it serves about 20 users. My e-mail server is Postfix; I'm using the daemonized version of SpamAssassin that I call from procmail in a system-wide installation, and I'm using Cyrus. The computer's used mostly for e-mail, but it handles light DNS and Squid duties too. SpamAssassin is always run as user cyrus on the Linux machine, so the bayes databases are in /home/cyrus/.spamassassin. I can reproduce this problem by running sa-learn, but it has also happened in the normal course of a day of processing e-mail. When the bayes database gets to a certain size, say 32 MB, and the SA reorganizes the database, it seems to create a bayes_toks.new file during that reorganization. Now as new e-mail messages come into the server, get passed to procmail, and the spamc program gets called, I think it forks spamd so that spamd can check the message to see if it's spam. In most cases, I think it detects that the bayes database is in use and it skips the bayes-related tests, and SA runs pretty quick. After several messages have been processed by spamc/spamd while one of the spamd processes is reorganizing the bayes database, invariably one or more of the forked spamd processes starts doing something (I'm not sure what) that takes all the processing time a process can get. If another message or two comes in and their spamd process runs away like this, the machine is a goner. It grinds to a halt and takes 5 minutes to process each shell command that I issue. So I usually do ps -afe, kill -9 the bayes reorganization process and the runaway spamd processes, rm the bayes database files, and that takes care of the problem. Unfortunately, the bayes databases are gone so SpamAssassin is not as good as it could be at catching spam, and everyone's frustrated because the e-mail system was unresponsive for 1/2 hour while this was happening. Does anyone else have this problem?
