Antony Blakey commented on COUCHDB-365:
---------------------------------------
The original error is in this code:
should_flush(_DocCount) ->
MeAndMyLinks = [self()|
[P || P <- element(2,process_info(self(),links)), is_pid(P)]],
case length(MeAndMyLinks)/2 > ?BUFFER_NATTACHMENTS of
true -> true;
false ->
case memory_footprint(MeAndMyLinks) > 2*?BUFFER_MEMORY of
true ->
[garbage_collect(Pid) || Pid <- MeAndMyLinks],
memory_footprint(MeAndMyLinks) > ?BUFFER_MEMORY;
false -> false
end
end.
The problem being that the second time memory_footprint is called the elements
of MeAndMyLinks may not be valid because of the preceding garbage_collect.
I fixed this by replacing that second call by this:
memory_footprint([self()| [P || P <-
element(2,process_info(self(),links)), is_pid(P)]]) > ?BUFFER_MEMORY;
> Replication hangs and won't restart

> Components: Database Core
> Affects Versions: 0.9.1
> Environment: Replicate to Ubuntu from OSX, both running R13B
> Reporter: Antony Blakey
>
> Partway through a replication I get this:
>
> {"error":"json_encode","reason":"{bad_term,{couch_rep,'-memory_footprint/1-fun-0-',2}}"}
> as the response from the replication request. Attempting to restart
> replication results in:
> [info] [<0.5511.0>] replication "1f78d088910dc73016c0b16b2fb84aac" already
> running at <0.4203.0>
> but the replication has hung.
