Hello,
with mod_jk 1.2.23 status worker there is the output
Next Maintenance
The first seems to be the countdown until next maintenance. But what does the
second number stand for? Could not find it in the docs.
Due to the way the maintenance feature is implemented, we can't be sure,
when *exactly* global maintenance it is happening. The two values are
the earliest possible and the latest possible time it will take for the
next global maintenance. Global maintenance is responsible for error
recovery (allowing workers in error state to be used again for requests)
and decaying load values for the balancer. The min and max times will
only be correct, if there are any requests at all during that time.
The uncertainty comes from the fact, that there is local and global
maintenance. Local means once *per web server process* (closing of idle
backend connections), global means once per web server.
Mladen added a separate maintenance thread for the next version 1.2.27
(off by default), that would make timing much more predictable.
Thank You,
Stephanie

Rainer
