bug, maybe

[Ginger Booth]

Guys,
    I hooked up a few graphs, and overnight, at a tawdry 6090 generations,
the graphs crashed the Swarm run:

    (Tcl -eval:) can't allocate data vector
        while executing
    "address@hidden@0x4005dfe0 element append address@hidden
    x40062128 { 6090 585 }"
    while evaluating: address@hidden@0x4005dfe0 element appe
    nd address@hidden { 6090 585 };
    (Tcl -eval:) can't allocate data vector
        while executing
    "address@hidden@0x4005dfe0 element append address@hidden
    x40062568 { 6090 154 }"
    while evaluating: address@hidden@0x4005dfe0 element appe
    nd address@hidden { 6090 154 };
    *** event raised for error: OutOfMemory
    No more memory available from the system.  Value of sbrk: %0#8x
    *** execution terminating due to error
    IOT trap (core dumped)

My bar charts shouldn't be taking any more memory as time goes on, so I
assume this is just the population graph, which would be two traces of
6090 points, on a machine with 48 Mbytes real memory (but there was another job
running, which might have hurt).

Just fyi, for consideration in designing your statstuff.

Ciao,
    Ginger
