Comment (by waddlesplash):
I managed to reproduce this, though the rate is much slower for me (0.1MB
every 3-10 seconds.) When it is occurring, more and more slab areas are
created, e.g.
{{{
slab memory manager: created area 0xffffffffb0801000 (240115)
slab memory manager: created area 0xffffffffb1001000 (240117)
}}}
So, I dropped into KDL and dumped all object caches (includes net_buffers
and the default malloc heap), exited, waited a while (without doing
anything), then did it again. Here are just the differences:
