Bug ID: 58806
Summary: HTTP/2 appears to keep workers in KEEPALIVE status
Product: Apache httpd-2
Version: 2.4.18
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: mod_http2
Assignee: bugs@httpd.apache.org
Reporter: l...@sce.net

mod_status output
I have recently enabled HTTP/2 via the mod_http2 module. I have noticed that
soon after doing so, the number of httpd processes increases. Looking at the
server status page it appears that the processes are remaining alive because a
thread is listed in KeepAlive status. I am enclosing a slightly sanitized copy
of the server status page.
This occurs with both the worker and event MPMs, running on Linux -
v3.11.10-29-default, (amd64 platform). Each worker process is set to terminate
after 10240 connections, via the following config entries:
StartServers 1
MinSpareThreads 2
MaxSpareThreads 20
ThreadsPerChild 16
MaxRequestWorkers 256
MaxConnectionsPerChild 10240
If I disable mod_http2, this situation goes away and the workers are recycled
properly.
