I encountered a situation last night where some of my trusted blacklists (for deletion) became unreachable for whatever reason (xxxx.blackholes.us, I see some chatter that they are down)

The Imail SMTPD32 service went into a cycle of running the ram up somewhere in the range of 200MB and then failing with a log entry of:
07:26 12:07 Network Layer(0000000000c20078) Get Buffer Alloc failed: 8

Which is likely the nic buffer overflowing trying to talk to the unresponsive RBL

I can reproduce this behavior at will by simply adding the failed blacklist

Did anyone else suffer similar issues recently? I narrowed it down to japan.blackholes.us as the one the was causing the most flagrant RAM run up
