Starting with 6.3.4, the action queues have a default batch size of 128 messages. +<h2>Default action queue enqueue timeout</h2> +<p>This timeout previously was 2seconds, and has been reduced to 50ms (starting with 6.5.0). This change +was made as a long timeout will caused delays in the associated main queue, something +that was quite unexpected to users. Now, this can still happen, but the effect is much +less harsh (but still considerable on a busy system). Also, 50ms should be fairly enough +for most output sources, except when they are really broken (like network disconnect). If +they are really broken, even a 2second timeout does not help, so we hopefully get the best +of both worlds with the new timeout. A specific timeout can of course still be configured, +it is just the timeout that changed. <h2>outchannels</h2> <p>Outchannels are a to-be-removed feature of rsyslog, at least as far as the config syntax is concerned. Nevertheless, v6 still supports it, but a new syntax is required |
