Hui didn't know this. So i should remove ALL settings and only set: ThreadsPerChild ServerLimit MaxRequestWorkers AsyncRequestWorkerFactor ? is this true? I'm missing some examples also considering MinSpare and ThreadLimit or are they no longer needed? > This is only a speculation from my side, to have a better idea of what's > happening it would be great to see how the Scoreboard looks like in > server status, and if the error status happens during specific events > like graceful reload for log rotation. All of them happened after a reload - but I'll recheck. I'm pretty sure that the /server-status page was no longer responding. Is there any other way to get the status of of httpd while it does no longer serve pages? > Hope that helps! As always, thanks a lot for your tests :) Greets, Stefan > Luca
