Hi.
panic: kmem_malloc(4096): kmem_map too small: 275251200 total allocated cpuid = 0; lapic.id = 00000000
man tuning
You probably need to reset maxusers to 128 or so manually since the auto-tuning is doing the wrong thing. Although this is usually a problem on 4GB systems.
I'll try to adjust it manually.
You aren't running any wierd nmbclusters/nmbufs values, are you?
Just a straight install and custom-kernel reg. NIC and SCSI.

You'll either want to raise the size of the kmem_map pool (this is where kernel malloc and UMA get their allocations), or decrease the maximum number of vnodes allowed (vnodes get allocated out of the kmem_map and are likely depleating it in your case). I run into this constantly; we worked on fixing it last spring by making the maxvnodes auto-tune itself better, but that seems to no longer be enough. Add one of the two lines to /boot/loader.conf:
kern.vn.kmem.size=350000000
or
kern.maxvnodes=150000
The first one is probably the better choice for you since the very nature of what you are doing demands that you touch a lot of vnodes.
