Hi everyone,
When using slabtop to display the cache size growing, I see that
kmalloc-1024 and kmalloc-256 are increasing about 200MB after 1 hour.
Is there any way to detect which kernel components cause this slab
increase?
Thanks a lot,
Brs,

Hello Naruto
I think you can do it by instrumenting call to kmalloc(). These days, eBPF is the hot stuff to try for this matter. See if it fits yours too.
