Running an Apache web server out of an IBM Softlayer server farm in Dallas. Evey so often, the Apache hpptd child process restarts then stops responding to page requests when it cannot access OSCP stapling. Seeing the problem now every few days.
The latest was this morning (all times MST) between 2:31 am and 3:01 am. Here’s a sample from the log file…
[Mon Mar 04 02:31:15.367980 2019] [mpm_winnt:notice] [pid 18232:tid 532] AH00418: Parent: Created child process 18324

Apache is restarted automatically every 5 minutes when not responding. The errors persisted until 3:01 am when the OSCP server appears to have started responding again and no more problems.
This issue has happened intermittently over the last week or two. I am looking at the option of just turning SSLUseStapling off as I need the sites up and running 24/7.
Not sure if this is an issue with Akami blocking the server farm’s IP range due to excessive hits or ???.
Here’s my Apache config lines…
Any ideas or insights would be greatly appreciated.
