riak-0.14.2 memory crash

Our system had been humming along fine for a week and crashed today
with almost no load. This is the only thing in the erlang.log:

=INFO REPORT==== 8-Jul-2011::16:46:14 ===
=INFO REPORT==== 8-Jul-2011::16:50:14 ===
=INFO REPORT==== 8-Jul-2011::16:51:14 ===
Erlang has closed.
Erlang has closed

Crash dump was written to: erl_crash.dump
eheap_alloc: Cannot allocate 1824525600 bytes of memory (of type "heap").

Looking in the sasl-error log I see that an erlang function I wrote
was crashing in some cases:

** Reason for termination = ** {error,       {phase_error,
{error,               {error,undef,
[{get_erl,past_events,                        [{r_object,<<"events">>,

So I definitely need to fix my code, but I'm wondering if this is
expected behavior that this would cause a memory leak that eventually
brings down riak? I thought if the process running my module crashed
everything would just be garbage collected and that'd be the end of
it. Any advice on the right way to approach this would be great,
