This processing was redundant and had a lot a drawbacks. For details, please see the <a href="v4compatibility.html">rsyslog v4 compatibility notes</a> which elaborate on the reasons and the (few) things you may need to change. +<h2>Queue Worker Thread Shutdown</h2> +<p>Previous rsyslog versions had the capability to "run" on zero queue worker +if no work was required. This was done to save a very limited number of resources. However, +it came at the price of great complexity. In v5, we have decided to let a minium of one +worker run all the time. The additional resource consumption is probably not noticable at +all, however, this enabled us to do some important code cleanups, resulting in faster +and more reliable code (complex code is hard to maintain and error-prone). From the +regular user's point of view, this change should be barely noticable. I am including the +note for expert users, who will notice it in rsyslog debug output and other analysis tools. +So it is no error if each queue in non-direct mode now always runs at least one worker +thread. </body></html> |
