If you let your test app run, and the file it creates grow and grow, how does the cache usage progress?
It stayed at about 1G.
Here is my test app, which tyies to capture the spirit of what the real app is doing. It demonstrates the cache growing issue on both 12.1 and 12.3.
That is not the real issue though - the file system cache will grow to max available on any system, without causing a problem. I think your problem is described in the link that Andrey Borzenkov sent. Your app needs a sustained, high IO-rate, and that is not quite what the standard Linux settings are set for.
Apparently. The surprising thing is that the app has many other files open as well. None are as big as these. But they are not so small either. There is some trigger point that seems to make this happen.
