I installed WordPress on my Ubuntu server. I only have 3 blog posts but it reaches max_connection within an hour. So whenever a user visits my blog it shows a database establish error. My log file has the following entry:
server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
[Mon Jun 20 06:30:21.877663 2016] [mpm_prefork:notice] [pid 43436] AH00169: caught SIGTERM, shutting down
My default max_connection is 200 now. I increased it to 1024.
Once i increase max_connection to 1024 it works fine. But I think that it’s not the real issue. For three blogs it makes 564 connections.
