At the end of this message are all the entries from 2 seconds of my maillog
from a crash today, starting with the last greylist action and ending with
the error message.
Prior to the crash, the connecting site ( tried to connect 18 times over a
period of 60 seconds. The last 9 attempts were made three at a time during
1 second intervals. The last triple occurred 2 seconds before the failure.
The connected site was h66-201-246-167.gtcust.grouptelecom.net
[66.201.246.167].
Can multiple dropped connections cause a problem with milter-greylist?
The last triple connection attempt look like this:

hmm, all *alloc()/*dup() calls seem to be assigned with a syslog in case
of failure. Should be visible in the error logs then.
What about running through valgrind or something similar. Whatever the
problem
is, it will be loggued for sure, maybe even faster than in real life as
those tools usually allocate more memory than requested in order to check
for
over&underflows.
