Hi, I have panic kernel on my server after errors:
server is within MinSpareThreads of MaxRequestWorkers, consider raising the MaxRequestWorkers setting
server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
This apache error can make kernel panic ?
I have updated the configuration of mpm_event in order to compensate for this (default value originally)
Old configuration :
StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxRequestWorkers 150 MaxConnectionsPerChild 0
New configuration :
StartServers 4
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxRequestWorkers 500
MaxConnectionsPerChild 0
ServerLimit 20
ServerLimit to 20 from 16 by default because with 16, the MaxRequestWorker is 400 not 500
i have a server with 4 cores 8 threads with 32 Gb of memory and NVME drive.
Memory usage actualy is : 31.09 GiB total / 26.11 GiB free / 25.5 GiB cached
What is the best configuration for apache mpm_event, i can set ?
Thanks for your help
