It even stops responding to ICMP ECHO, but output from netstat -m is perfectly normal: 87/592/524280 mbufs in use (current/peak/max): 87 mbufs allocated to data 83/350/131070 mbuf clusters in use (current/peak/max) 848 Kbytes allocated to network (0% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines This problem is repetable, it occurs *every time* after about 30 minutes of uptime, unless I decrease amount of RAM from 640 MB to 128 MB. NMBCLUSTERS and/or maxusers tuning doesn't help either. On GENERIC kernel, first ENOBUFS error occurs after 10 minutes of uptime. >How-To-Repeat: Perfectly repetable on my hardware, occurs every time with 640 MB, doesn't occur on 128 MB RAM. >Fix: N/A >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
