Not Solved Thoughts on reducing memory usage?
Not Solved
To sum up the issues I am having with memory usage:

1. Resting Physical Memory Usage is around 25-27 MB when just viewing the index, and around 33 MB when someone is viewing a post or posting.
2. This increases during weekends, and last weekend the forum just crashed with a 503 error.
3. An example load when loading the forum is: Generated in 156 ms (77.01% PHP / 22.99% MySQL), SQL Queries: 23 / Server Load: 0.83 / Memory Usage: 16 MB.
SQL Queries: 23 / Server Load: 0.93 / Memory Usage: 16 MB
I am not sure whether this is related to tasks, or some mysql error. 

I am less inclined to think it is entirely related to plugins, as even if I set it to Disable All Plugins, and Uninstall/Delete the plugins, the Physical Memory Usage is little different, and the same with the load time. 

After the forum came back after the crash, I removed some plugins that weren't necessary, and hopefully that helped. But my concern is that it might crash this weekend again or hypothetically if more users than usual go online and post.

Crash occurred on the 19-21st of this month, and this is what I got in the Resource Usage snapshot:


Other info:
  • MySQL Disk Usage is about 11.99 MB.
  • Forum address is:
  • There are about 201 users registered, but they are never on at one time.
  • Database is Mysqli. 
  • File Verification shows no errors.
  • Forum themes are Default, NetPen Pro, and FunkyOne.
  • There are not a lot of visitors to the forum, and at any one time there are maybe three or four online, as most users use discord. 
  • Having Google Ads does slow down the forum load, and make the forum load longer, but might as well have the revenue.
