Hmm, I have added some log about the R_Malloc error in rtrequest1. I
suspect your panic is caused by it.
Could you retry the latest master @ 38c2eb266c21ce17c37c1b4b8d2a6bc8c73aa26c?
Try locate the panic messges like:
rtrequest1: alloc rtentry failed on on cpuX
The default kmalloc limit of M_RTABLE could be too small in your case.
If it is caused by the kmalloc size limit we may fix it w/ some
simple changes.
Best Regards,
sephe

Hi,
I'm using DragonFlyBSD to make border routers.
When loading routes on SMP systems ( 382492 routes, 375250 ipv4 + 7242 ipv6 ),
the kernel panic.
The test machine is DragonFly v2.13.0.781.gfaddf-DEVELOPMENT (i386) and the routes are injected by Quagga 0.99.17.
The Backtrace is as follow :
