I have implemented a custom whitelist/blacklist with a milter. This milter has been working smoothly for a nearly 2 years now on multiple machines
But now On 1 machine even if the load is very low and there is ample free memory once the number of smtpd processes reaches 300 ( I have set limit to 650 ) some milter processes start timing out. Some smtp connections only are affected most still go thru I restart and then everything works fine again for some time How can I debug this ? Thanks Ram
