Looks like I have this issue again (pegging 4 core cpu) and resetting
the process doesn't make a difference. Not sure what is causing it
but it does slow down spam detection to 40-50 seconds for many emails.
Any ideas what I can look at or do to resolve this?
Check the message sizes. As part of the newest spam storms we've noticed
that a lot of the messages are huge (65536++). I suspect this might
impact throughput as large buffers are allocated and moved around to
handle these messages. This kind of thing has also been known to cause
NTFS to crawl.
Please let us know what you find.
If you are not already doing it -- you should consider blocking
connections using the truncate blacklist. No sense taking on some of
these messages if they can be eliminated up front.
