This machine has one 3Com Etherlink III (3c5x9) card. When someone using socks-enabled client in a client machine tries to FTP something, the server's net adapter hangs. The main symptom is: # ping 192.168.0.1 ping: sendto: No buffer space available ping: sendto: No buffer space available ^C # netstat -m 246 mbufs in use: 109 mbufs allocated to data 128 mbufs allocated to packet headers 8 mbufs allocated to protocol control blocks 1 mbufs allocated to socket names and addresses 74/266 mbuf clusters in use 562 Kbytes allocated to network (31% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines It seems that the only way to recover this problem is re-booting the machine. >How-To-Repeat: FTP'ing something with a FTP client under sockscap (win95). It does not happen every time, but most of the times. >Fix: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
