:Strange, as I have 3GB of memory. Is there a memory leak somewhere?
:I just build 1 or 2 packages (distfiles are already fetched), no other

I thought I had fixed those. Damn.

    Can you get a crash dump from the panic?  And upload it to your
    leaf account?

Hm, I couldn't reproduce the panic after setting "dumpdev" correctly in loader.conf (it refered to a non existing partition). I also used
hw.physmem="2G" (instead of the 3G of memory).

I try again without the hw.physmem setting and see if I can reproduce it. Or could it be related to maybe dumpdev (or the missing swap partition)?



    This does sound like a memory leak but it could also be something
    else.  HAMMER keeps track of all those allocations so I should be
    able to figure out what is going on from a crash dump.
