Hi, We see an continuous increase in slab size of 1GB for slab cache named "size-16384" in a system. The system is stable and sending/receiving bulk amounts of packets. "/proc/slabinfo" Initial Value: size-16384(DMA) 0 0 16384 1 4 : tunables 8 4 0 : slabdata 0 0 0 size-16384 9247 9247 16384 1 4 : tunables 8 4 0 : slabdata 9247 9247 0 "/proc/slabinfo" Final Value: size-16384(DMA) 0 0 16384 1 4 : tunables 8 4 0 : slabdata 0 0 0 size-16384 75023 75023 16384 1 4 : tunables 8 4 0 : slabdata 75023 75023 0 Can anyone please tell us what kind of functions in kernel need to allocate an object for "size-16384"? In what possible scenarios are these slab objects allocated?
