With the mpm limits, the webrunner fails often to instanciate because of the error in promise below : 2020-04-28 07:45:23 slapos[4284] INFO Checking promise monitor-httpd-listening-on-tcp.py... 2020-04-28 07:45:28 monitor-httpd-listening-on-tcp.py[4284] ERROR ERROR: HTTPSConnectionPool(host='2001:67c:1254:e:8e:66f4:0:4e9c', port=8386): Read timed out. (read timeout=5) Checking the open connection with ss, I could find many lines like : tcp CLOSE-WAIT 518 0 [2001:67c:1254:e:8e:66f4:0:4e9c]:8386 [2001:67c:1254:e:8e:66f4:0:4e9c]:49540 So apache was too slow to answer, or busy doing something. Connections to it were getting queued, making promise fail, making another "slapos node instance" required, creating more frozen tcp connections. For this change, I took inspiration from the webrunner apache config, which doesn't define these parameters at all neither. I did a fast performance check, with this commit, when apache is started it consumes ~40Mo. I didn't check before this commit, but I doubt it would be much less than that.
