Umm, no, not until now.
The result is the same:
Unread portion of the kernel message buffer:
panic: kmem_malloc(131072): kmem_map too small: 335331328 total allocated
cpuid = 0
Uptime: 15m25s
Physical memory: 1015 MB
Dumping 371 MB: 356 340 324 308 292 276 260 244 228 212 196 180 164 148
132 116 100 84 68 52 36 20 4
#0 doadump () at pcpu.h:195
195 __asm __volatile("movl %%fs:0,%0" : "=r" (td));
This is with the default settings, so:
vm.kmem_size_max: 335544320
vm.kmem_size: 335544320
vfs.zfs.arc_min: 16777216
vfs.zfs.arc_max: 251658240
