Apache 2.4.33 with mod_jk 1.2.43 keeps shutting down when no Tomcat
worker is available
Hi,
we have Apache-2.4.33 as a frontend to a bunch of Tomcats using
mod_jk-1.2.43 as load balancer. Since we upgraded to this combination, we
observe Apache shutdowns as soon as the last Tomcat worker is down. This
has not happened before up until apache-2.4.33+mod_jk-1.2.42.
error-log is pretty non-informative:

Is there anything known along this lines?
Thanks

Hi,
please ignore. There was another component (corosync) that I did not
consider. When all tomcats are down, that ends up in a 503 which confused
the HA software ...
Happy Weekend
