Comment 27 for bug 1924298

In Tomcat versions 9.0.56 to 9.0.58, this message was sometimes emitted in error; this was fixed in 9.0.59. Since 9.0.63, the log message also explicitly recommends to use Kernel 5.10 or later, but I am not seeing that in any of the logs reported here, so these Tomcat versions must be older than 9.0.63.

For those of you who have recently reported seeing this on up to date focal and jammy versions with Kernel 5.15, please update Tomcat to a recent version (at least 9.0.59) and report back.
