This looks identical to the situation there. However, I have only config'd 4K of mbufs. Here's some sysctl stuff if it helps.. me# sysctl kern | grep mb kern.ipc.nmbclusters: 4096 kern.ipc.mbuf_wait: 32 kern.ipc.mbtypes: 178151 4294789573 4 0 0 0 0 0 0 0 0 0 0 0 0 0 kern.ipc.nmbufs: 16384 I've also set maxusers to 256. >How-To-Repeat: Not sure if a different machine would do the same, yet, but add NMBCLUSERS = 4096, change maxusers to 256 in GENERIC, build, reboot. Try netstat -m. >Fix: not sure, yet. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
