lsm_file_cache memory usage high
Asked by
norman shen
Hello,
I have found an unusual large amount of memory usage by `lsm_file_cache` which seems to be patched back to ubuntu 18.04.
after running slabtop, it is showing
1210374840 1210374840 100% 0.02K 7119852 170 28479408K lsm_file_cache
which should imply that 20GB is used by lsm_file_cache while the virtual machine only gets 40GB..
the virtual machine has been running for 443 days
root@mgt05:~# w
08:43:50 up 475 days,
and by the time the command executed, there are around 1million files opened
So what should I do if I want to release some of this slab? thank you.
Best,
Norman
