okay, a few of you will remember by griping about tcp performance on a laptop with the 3c589d card. well, now I get to experience it all again. right now I have: * a box which can't ping, error message: ping:sendto:No buffer space available * can't be pinged * froze during an ftp * has two non-closed tcp connections, one with a Send-Q of 17520 (CLOSING) and the other has a Send-Q of 106 (LAST_ACK) * netstat -m tells me I have 112 mbufs in use, 34k of which is allocated to network (94%), 64 are for data, 45 for headers, 2 for pcb's, 1 for socket names/addresses and 9/10 mbuf clusers in use. It also says there have been no denials or delays and 0 calls to the drain routines. As far as networking is concerned, the box is fucked. The only hope I have (and what I am doing) to make it work is to reboot. After the reboot... Attempting to ftp to it from solaris resulted in this: 200 PORT command successful. 150 Opening BINARY mode data connection for 'p1' (100663296 bytes). netin: Connection reset by peer 421 Service not available, remote server has closed connection Lost connection No control connection for command: Error 0 No control connection for command: Error 0 ftp> (no, I didn't hit ^C or run anything else, just let it "happen"). if I run "tcpdump -p" on a screen, it seems work okay. btw, I'm quite prepared to blame the zp driver - it fails to properly detect the device when I boot up FreeBSD after running Windows 95. Requires a cold boot to make the card detectable (to FreeBSD) again. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
