Quote one from your dmesg output, > CURVNET_SET() recursion in hhook_run_socket() line 3700, prev in > ether_= input_internal() > 0xfffff8000a4f7040 -> 0xfffff8000a4f7040 > KDB: stack backtrace: > db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00634= c16f0 The root cause is that you have enabled `VNET_DEBUG` option in the kernel b= uild config, KERNEL-14.2 in your case. That option is field for debugging purpose which is useful for developers. End users will barely want to enable it. The output is harmless but certainly will hurt performance in critical / fast p= ath. To **fix** it, just disable the `VNET_DEBUG` option.
