I have gone as low as 10,000 for kern.maxvnodes, and it still
Panics with "kmem_map too small". How low should I go?
I also built a kernel with KVA_PAGES set to 512 and it paniced
the same way (without changing kern.maxvnodes). When I also
changed maxvnodes to 100,000, then the system hung instead of
panicing...
Anything else I can try? Keep in mind I'm running SMP. Should
I try it with a UP kernel?
Thanks,
John
