Perfect spamsnake allows all emails through at 3am
I've been running the perfect spamsnake on Ubuntu server 8.04.2 for about 8 months, all in all it has been superb, but I do have two issues, though they may well be connected.
Our spamsnake feeds into a secondary mail filter box which has pretty graphs etc and is then used as the fail-over for spamsnake.
Ubuntu is set to run it's daily.crons at 3am every day, and at this time for around an hour sometimes a bit longer, our second mail filter reports a massive increase of mail from approximately 200 an hour to in excess of 2000 often in excess of 4000 emails per hour.
The second issue is that approximately every 2 weeks (though it isn't exact) the system fails. all mail stops flowing through it, it is not accessible through the network via pings, ssh etc, open up the console and it is as if it is part way through a script but just hanging, the only option is to cold boot it as it becomes unresponsive to keyboard. This in itself causes problems as the mailscanner and gld_db databases both need repairing.
Once the system is back upo there appears to be no mention of an issue in the logs, though I could be missing lots as I'm not all that savvy when it comes to the log files.
Has anyone come across similar issues, and/or know where to look to resolve the problems?
