Alright this is kind of puzzling to me. We are using ASSP version
2.4.5(15162) and also using MYSQL for our database backend. When I send
a request to ASSP for analyzing an email I get a weird response back in
the email. I get the Bayesian analysis back just fine, but the HMM is
blank. DoBayesian and DoHMM are both set to score in my config. Under
the section for Hidden-Markov-Model Spam probabilities the results come
back as follows:
*combined HMM spam probability*: got no result because the HMM database
is empty
*HMM confidence*: 0.00000000
*corpus confidence*: 1.00000000
Which is really odd, here's the last section of my rebuild from this
morning:
Oct-28-15 07:15:58 Spam Weight: 8,312,860
Oct-28-15 07:15:58 Not-Spam Weight: 8,314,034
Oct-28-15 07:15:58 Corpus norm: 0.9999 - (very good - balanced)
Oct-28-15 07:15:58 Corpus confidence: 1.00000000
Oct-28-15 07:16:03 Start populating Hidden Markov Model. HMM-check is disabled
for this time!
Oct-28-15 07:16:03 start populating Hidden Markov Model with 4,282,658 records!
Oct-28-15 07:16:46 Finished populating Hidden Markov Model with 4,282,658
records!
Oct-28-15 07:16:46 Finished populating Hidden Markov Model. HMM-check is now
enabled again!
We recently switched our rebuild to use the BerkleyDB for rebuilding the
spamdb. Here's a snippet from the top of my rebuilddebug.txt file:
Oct-28-15 06:00:00 rebuild debug output is enabled to
c:/assp/rebuilddebug.txt
Oct-28-15 06:00:00 RebuildSpamDB uses BerkeleyDB for temporary hashes
Oct-28-15 06:00:00 RebuildSpamDB uses BerkeleyDB-ENV with 50.00 MByte
Oct-28-15 06:00:00 RebuildSpamDB-thread rebuildspamdb-version 7.11
started in ASSP version 2.4.5(15162)
Oct-28-15 06:00:00 RebuildSpamDB will create a Hidden Markov Model
So is there something I am missing here? I seem to remember that before
we switched to the BerkleyDB for rebuild the HMM section populated
information just fine. Now the report claims the HMMdb is blank. Is
there something wrong with the BerkleyDB rebuild?
Here's the version we are using for the BerkleyDB: (Directly from the
ASSP email interface)
BerkeleyDB 0.51 / 0.42 enabled
BerkeleyDB_DBEngine 5.3 / 4.5 enabled
