Hi, We've just upgraded our old qmail server to a new qmailtoaster set up,and its mostly running ok, except for a few problems.
we had a large influx of mail delivered to local addresses today, and it seems to have clogged up the system. I've got a high enough concurrency remote (tried 10/20, and up to 60) but according to the send logs, it doesn't want to deliver or process more then one at the time. Is this due to the injection of lots of mails at one time? It feels like there should be a lot more qmail-local processes appearing, but i can't see if and where that should happen. If it stopped going from 1 to 0 and back to 1, and concurrently delivered locally to the disc at closer to capacity, the server would run a whole lot better. This doesn't seem to be aproblem with remote, which is sitting happily on much higher numbers (currently at 20 due to me trying to clear the local queue) The whole queues at about 13000, and preprocessed is about 5000 at this point in time, most of them are local delivery. The other question is system load, the old qmail ran on older hardware, and seemed not to be too overloaded, but this current server runs at about a system load of 10 or more whenever there's about 100 emials in the queue. It seems rather excessive, but i'm not sure if its expected or not. Thanks, Daniel
