Another update to share with you what MVLC is doing with our Apache configuration for Evergreen.
We found last week with the MaxMemFree setting at 16 and MaxRequestsPerChild at 1,000 that we were getting more texts from our monitoring software about the load being high on our Evergreen server. We thought this might have to do with more frequent turnover among the Apache child processes, so we adjusted MaxRequestsPerChild back up to 10,000. However, during overnight monitoring, we discovered that this made the situation worse, or at least put us back where we were before trying all of these changes.
In the end, we have set MaxRequestsPerChild to 5,000 while leaving MaxMemFree at 16. We've been running this configuration for several days, including over the weekend, and things seem to have really settled down on our server. You may have to experiment with the settings to find something that works for you if you think you are having this issue.
