Hi, I have dozen production FreeBSD firewalls that been working for a year and some, without any problems under heavy utilization. As a matter of upkeep/security, I cvsup them and go thru the buildworld, kernel, mergemaster, etc; haven't had much problem. In the last couple of months, upgraded to 4.6 and 4.7 using RELENG_4 with again no errors, however, now under a light smurf attack, I get: panic: icmp_error: bad length syncing disks... 1 done Uptime: 1h12m58s Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... I have found couple of posting on FreeBSD sites, google, dogpile, etc pointing to a patch for netinet/ip_icmp.c which seems to have been incorporated into the 4.6 tree; not sure though. I have tried building the kernel with RELENG_4_7 to no avail still panics. Also tried to down rev the kernel to 4.4, 4.5 using the kernel file on the same machine that I had saved prior to upgrade, which is holding up better, but still panics frequently. Hardware: Dell PowerEdge 350, 2 built-in Intel nic cards, 256 meg of ram and only doing ipfw. The kernel is built with options BRIDGE. Don't know what other info you might be interested. Deeply appreciate any help or info. Regards, Patrick Soltani To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
