  • SpamAssassin at Work | OASIS Staff Blogs
    NFS safe locking for the databases and I didn t notice a change I converted the databases to MySQL using MyISAM This lasted longer but eventually after a few hours developed a large enough database that table locking became a really limiting factor I converted those databases to InnoDB which should have helped with it s ability to use row level locking It lasted longer again but only about a day or so before it got out of hand Finally I gave up and disabled Bayesian filtering and let SpamAssassin do all the other stuff it did but a little more spam was getting through and I wanted to get it working That s the setup in a nutshell The solution I came up with was to use two databases The premise of my adjustment is that a Bayesian database that is static but only a few hours or even a day old ought to be accurate enough for the decision making on incoming spam detection I created two databases both using MyISAM for it s quick insert select capacity One is called spamassassin and is configured as a normal database The other is called spamassassin read and is used as the read only decision making database I hacked up the SQL pm file a bit that SpamAssassin uses to query the BayesStore module databases so that all the select queries in the decision making functions were coming from spamassassin read while all the storage functions that were learning from new messages were writing into the normal spamassassin database Finally I setup a script that operates in a couple steps First it adjusts the SpamAssassin configuration file local cf so that it stops using Bayesian filtering altogether and reloads SpamAssassin It waits a few seconds for any potential ongoing queries to stop sends a FLUSH TABLES command to the MySQL server then rsyncs the spamassassin writeable database to the spamassassin read database It packs the spamassassin read tables with myisampack to make them even more optimized for read performance and then it reindexes the tables as necessary Finally it turns Bayesian filtering back on in the local cf configuration file and reloads SpamAssassin again All in all the script takes a few minutes to run During that time SpamAssassin is still running and letting mail in but it s just slightly less effective without Bayesian filtering There s no downtime just slightly less effectiveness for a few minutes Each time the script runs the decision making database spamassassin read is refreshed with up to date information I ve attached a number of weekly graphs of various server statistics The server in question here is running with 2GB of memory and dual AMD Athlon MP 1600 processors and a 200GB IDE disk It s by no means the fastest machine around but decently capable The problems I had before are at the left of the graphs and are pretty easy to spot The latest performance numbers are more toward the right

  • Trying to give back... | OASIS Staff Blogs
    various modules I ve also taken a couple of custom modules I ve been using both for sites OASIS runs and for sites I manage or have managed in my out of work time and created Drupal projects to manage them I ve filled out my Drupal profile a bit too The first issue someone filed against one of my new projects was an offer to help with testing and development should I need it The project itself didn t even have any releases yet as I hadn t finished filling out the project page The description was all that enticed the other user to offer help and that feels pretty good Essentially I ve been using free and open source software for a long time now but this project is the first one where I ve made a somewhat significant and publically useful contribution I m relatively proud of that and hope to continue pursuing this kind of collaboration in the future Add new comment Navigation Latest images About this blog Neil Schelly Senior Systems Administrator hopes to be able to share the experiences that he thinks others can benefit from as he builds systems and networks to deploy

  • Tickets are great... when there are none! | OASIS Staff Blogs
    I can play with all the interesting new technologies that I ve been meaning to look into read about setup applications to test them etc That s the point when I can step back and look at all the systems I m running and see which ones could maybe use an upgrade because while it s doing what it needs to I imagine a way it can be done better At least to some degree that s the point at which I can lean back in my seat and kick my feet up and watch pretty graphs on my screen that I know will let me know when something requires my attention Zero tickets is the time I look forward to trying out some new ticketing helpdesk solutions since while what we have works everyone knows it can work better Zero tickets would be nice indeed But I ll settle for 21 today I m happy to begin my week with such a clean work queue and some clear goals to get into the teens N Add new comment Navigation Latest images About this blog Neil Schelly Senior Systems Administrator hopes to be able to share the experiences that he
