(In reply to David Gordon from comment #0) Can you show _exact_ kernel messages before and during the panic, say, 10 lines before the panic message itself and then everything that follows it ? We do not have 'secondary' panics, so the three lines you demonstrated are puzzling, at least. It could be that you get two panics, each on the its own CPU, but again, I need to see precise messages first. Keyword: crash – in lieu of summary line prefix: [panic] * bulk change for the keyword * summary lines may be edited manually (not in bulk). Keyword descriptions and search interface: <https://bugs.freebsd.org/bugzilla/describekeywords.cgi> Never able to reproduce and did not get any followup information. |
Created attachment 172415 [details] Crash stack trace Consistently crash FreeBSD anytime transfer rates raise above 2Gbps (every few days). See attached file for kernel stack trace. FreeBSD is running nas4free and is installed as a virtual machine over ESX 6.0u1 and mounts files to be shared over iscsi from an EqualLogic SAN. Once disks are mounted, NFS is used to share the files to the network. ESXi, N4032 switch, and nas4free use MTU of 9000+ and are configured to use a lossless priority VLAN for SAN traffic. I would be happy to answer any questions about our setup to help resolve this bug.
