Hi,
netstat -m produces following output on my machine, running 4.8-RC:
21732/22336/96000 mbufs in use (current/peak/max):
21732 mbufs allocated to data
20733/21260/24000 mbuf clusters in use (current/peak/max)
48104 Kbytes allocated to network (8% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
I tracked the percentage of mb_map in use. It reached 70% and then
wrapped back to 0%. Why does it happen? A bug?
There seems to be a problem with booting up 4.8-RC on a 4GB machine.
The kernel reaching multiuser mode produces message about
unability of allocating new u_map and panics. This is HyperThreading
enabled machine (2+2logical CPUs). Any ideas?
Thanks. /S
