There is this patch, but it probably won't help with the FD_SET limit: http://qmail.org/big-concurrency.patch It should be easy to change select() to poll(). > Anyway, if I > remember correctly, it's qmail-queue that actually dies when you go > over the limit.

It communicates with qmail-rspawn, which spawns qmail-remote processes to do the deliveries. qmail-queue only reads from the process that invokes it (or whatever is connected to fd 0 and 1). -- David Phillips <david at acz.org> http://david.acz.org/ _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
