What you're seeing is the result of packets being rejected after smbd crashed. Icmp bandwidth limiting had nothing to do with samba crashing, so don't bother fiddling with it. What you should do is use gdb to generate a backtrace from smbd's core file and see if any samba experts can help you figure out what's going wrong. Mike "Silby" Silbersack ---- Hi. I'm seeking suggestions for sysctl variables to use on a highly-taxed mission-critical file-server. This computer exports two 630GB arrays via SAMBA over gigabit on 3ware escalades. Anyone have any tips? The reason I'm asking is because smbd has been dropping processes lately. I recently added more render engines to our stack, so the file-server seems to be choking somewhere. dmesg shows: -snip- Nov 21 04:33:15 fnord /kernel: pid 1866 (smbd), uid 1005: exited on signal 6 Nov 21 04:20:01 fnord /kernel: Limiting icmp unreach response from 208 to 200 packets per second -snip- ---- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
