>Description:
Every 2 weeks I'm getting the following panic:
kmem_malloc(4096): kmem_map too small: 168394752 total allocated
vmstat -z on vmcore shows that most of kernel memory is used by
mbufs:
ITEM SIZE LIMIT USED FREE REQUESTS FAILURES
mbuf: 256, 0, 458820, 6, 2811418298, 7
but `vmstat -m' and `netstat -m' doesn't work:
# vmstat -M vmcore.4 -m
vmstat: memstat_kvm_malloc: invalid address (0xc0a01ffd)
Type InUse MemUse HighUse Requests Size(s)
# netstat -M vmcore.4 -m
netstat: memstat_kvm_all: invalid address (0xc0a01ffd)
The machine works as PPPoE router with mpd 5.0, so multiple netgraph
nodes are created.
