Hi,
I'm working with a box that is apparently running out of mbufs:
looutput: mbuf allocation failed
looutput: mbuf allocation failed
All mbuf clusters exhausted, please see tuning(7).
Looking at netstat -m, I get the following:
144/9472/26624 mbufs in use (current/peak/max):
134 mbufs allocated to data
10 mbufs allocated to packet headers
94/6656/6656 mbuf clusters in use (current/peak/max)
15680 Kbytes allocated to network (78% of mb_map in use)
95798 requests for memory denied
102 requests for memory delayed
0 calls to protocol drain routines
What is the difference between the "mbufs in use" line and the "mbuf
clusters in use" line? The clusters are showing that a max was exceeded,
but not the mbufs line at top.
Looking at tuning(7) and reading up in the archives, it looks like I
do need to bump up nmbclusters in loader.conf, and possibly bump
down the tcp socket send/recv space.
Can anyone clarify the netstat output for me?
Thanks,
Charles
