Federico,
Your diagnosis is correct, that freeze can be the result of reaching the
limit for UVM amap allocations. These get used by the kernel to describe
anonymous memory mappings, and mmap malloc() puts the UVM subsystem
under a higher load of those, eventually

It seems to me that under amd64 the UVM Amap usage is much higher then

it seems not enough.
That's probably because the code allocates in multiples of

Indeed it looks suspicious. Not my area, though, so I'd have to look at
the code to know the exact consequences. But yes, it's a possibility.
Can you break into ddb?
-p.
no, I can only ping the server or change tty (ctrl alt fn), but I can't type
anything.
