Hello! For a long time I was looking for the cause of the server load, not a single process eats anything especially, etc. And then I checked cat /proc/meminfo and
this is what I got:
cat /proc/meminfo
MemTotal: 2054064 kB
MemFree: 83460 kB
Buffers: 91716 kB
Cached: 1695844 kB The
cache reserves 1.6 GB of 2 GB of RAM on the server. How can I limit this, I tried to google but found nothing. Thank you in advance.

Nothing needs to be restricted. All available memory is used for cache. If an application needs a lot of memory, the OS will automatically release it.

Don't touch the cache. Run memtest86 if the server is physical.
Hangs are only due to kernel level issues. Do you have kernel panic and other segmentation faults in dmesg output?
