I think you may be right, as it seems to be fine now? I even put my
spamdyke timeout back to 5 second delay.
Are there any parameters that I can adjust to help with this type of issue?
There were no cpu/memory constraints?
If you dig back through the archives there mention (maybe even by me -
if not, email me off-list) of adding an iptables rule to throttle storms
like this. On production servers I drop IPs that attempt to connect more
than 10 times in a 60 second period, and I reset that after 6 hours.
Maybe adjuts your blacklists some. Depending on your load you may be
exceeding the number of "free" lookups allowed by spamhaus and you may
need to look into their commercial feed.
