Hello List,
found today an abnormality in my apachestatus for some servers.
There are a lot of "h2 idle, streams" in apachestatus. This looks like
this:
14-0 28241 0/41/41 K 0.25 128 1 0.0 0.10 0.10 ip.ip.ip.ip h2 idle,

Some servers have hundreds of this, never noticed this before.
This connections have status K or W. Ist this a kind of attack to reach
MaxRequestWorkers?
It seems the number of this connections can be reduced by reducing
H2MaxWorkerIdleSeconds to a lower value.
Apacheversion is 2.4.27.
What should i do now?
Thanks,
Hajo
