Resource limits reached

Since a month, I am experiencing an issue with my website, where the resources used reach their maximum. Specifically, an error message is displayed when visiting my website: “Resource limits reached”. If I open cPanel, I see these statistics:

1. Number Of Processes: 165?/?165?(100%)
2. CPU Usage 100?/?100?(100%)
3. Entry Processes: 150?/?150?(100%)

To resolve the issue, I have to rename the public_html folder, temporarily replacing it with another one that I use to put my website in maintenance mode. After about two minutes, the website resources return to normal, something like:

1. Number Of Processes: 11?/?165?(6.67%)
2. CPU Usage 0?/?100?(0%)
3. Entry Processes: 0?/?150?(0%)

When I see these statistics, I can restore the original public_html folder. After restoring the original public_html folder, two things can happen:

1. The problem doesn’t occur for a couple of days.
2. The problem occurs again after about 3/4 minutes, and I have to repeat the above-mentioned steps a certain number of times.

Understanding the cause of this issue has been quite complex. However, during the last two instances, I performed a specific test that shed light on the root of the problem. After facing the problem repeatedly, and after restoring the public_html folder, I immediately disabled the SQLite Object Cache plugin before resources reached their maximum, and the issue stopped happening. I tested this twice in different days and reached the same conclusion each time: the problem is caused by the SQLite Object Cache plugin

Unfortunately, I am aware that solving such a problem is very complicated, especially when there are no errors present in the log files. I think I also understand the situation of processes, such as process B doesn’t know what process A is doing and when it ends. But I think it was worth noting the existence of this issue. Considering the timeout issues with the past updates, I’ve always suspected that the cause could be SQLite Object Cache. However, I chose to wait a month to conduct the appropriate tests to confirm if it was indeed the cause before reporting it here.

I believe it’s important to note that this also happens when my website has very low traffic. Despite the plugin having this issue, I remain confident that it is the best option for safeguarding resources. Addressing this problem or implementing specific workarounds could greatly enhance the overall user experience and ensure smoother plugin functionality.
