I guess, you also have increased limits in login.conf? > I know filter-spamassassin is expensive, and I've pre-forked (now 30) > children (currently the box has 8 cores and 8GB RAM, both apparently > underutilized), but the only way I can ensure the system doesn't get > bottlenecked is to throttle the connections at pf. What do you see from spamassassin spamd in the logs (maybe enable debug), are the sessions finished by spamd? Have you tried the limit option of filter-spamassassin? Your fstat output also shows connections to clamav, so maybe not spamassassin the culprit here? > Also, limits are present: > > limit session max-mails 40 > limit scheduler max-inflight 30 > but it doesn't appear to change the behaviour - the queue is never full, > just a ton of connections.. I assume hanging and dead, but hard to debug without logs, so: Please add your exact versions as mentioned above, full config (including spamassassin spamd and clamd tweaks), logs from smtpd -dv -Tall and fstat as well as smtpctl show stats output to #698, thanks! -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org
