Hi all, I observed something funny with our new cyrus/postfix/amavis installations running on 6.2-STABLE checked out on April 1st (no, I'm not joking). They are running symon to grab performance data and I saw the memory total becoming less and less. Now I know that adding up free+active+inactive != total ram BUT *all* other FreeBSD machines we are running show a more or less constant sum. I uploaded two pictures showing the trend here (They are i386 machines with 4GB RAM, FreeBSD reports 3.3GB as usable): http://coyote.dnsalias.net/ms1-day.png http://coyote.dnsalias.net/ms1-week.png Now after doing some heavy IMAP testing (cyrus reconstruct of big maildirs) the system froze to a complete halt. Stupid me already rebooted the machine, tomorrow I'll try to break into DDB when it happens again. I also started recording top(1) memory output and sysctl vm.zone output. The main questions is: Were there any known memory leaks at the start of April? Any patches I should blindly try before spending several days on debugging this? Thanks! Uli
