Hi,
I just did some stress-testing on milter-greylist in order to test its
memory consumption and it seems that there are some leaks to be found.
The test was done with smtp-source(1), had a duration of about 30
minutes, started with:
smtp-source -4cA -s 100 (...)
at some point continued with:
smtp-source -4cA -s 500 (...)
and ended with no mails being sent at all.
Take a look at the top-output (printed every 15 seconds):
,---- Total size of the process (text, data, and stack) given in kilobytes.
/ ,-- Resident memory: current amount of process memory that resides in physical memory, given in kilobytes.

Content of the (striped-down) greylist.conf:
user "smmsp:postfix"
pidfile "/var/milter/mgrey.pid"
dumpfile "/var/milter/mgrey.db"

quiet
lazyaw
timeout 1d
autowhite 10d
report delays
racl whitelist addr 127.0.0.0/8
racl whitelist default nolog
dacl whitelist default nolog
The stress tested environment was NetBSD 4.0.1 (no swap configured),
milter-greylist 4.1.6, built through pkgsrc using the following
configure arguments:
--with-user=smmsp
--enable-dnsrbl
--with-thread-safe-resolver
--disable-drac
--with-libspf_alt=/usr/pkg
--enable-postfix
--enable-spamassassin
--without-libintl-prefix
--without-libiconv-prefix
--prefix=/usr/pkg
--host=i386--netbsdelf
--mandir=/usr/pkg/man
Any ideas?
Thanks,
