I’ve been running MIAB for years, but just today
sa-learn started going crazy, spawning hundreds of processes and eating all available RAM. I saw that this has come up before, but rebooting doesn’t help. Restarting the dovecot process makes everything calm down, but it soon restarts. I have disabled it by commenting out the pipe commands in
/etc/dovecot/conf.d/99-local-spampd.conf, but obviously that is just avoiding the problem by introducing another.
I’ve no idea why this is going amiss – any pointers?
