timeout during dumping keys in large bucket

[pallinger]

I'm trying to dump data from a bucket for migration:
java -jar riak-data-migrator-0.2.6.jar -d -r ./ -b BUCKET -h IP -p 8087 -H 8098

The above operation exits with an exception:

Dumping bucket BUCKET

During the above operation, it dumps a significant amount of keys in BUCKET/bucketkeys.keys (about 1.3M of 2.2M keys).

@pallinger - what version of Riak are you using?
Unfortunately, there is a hardcoded 60 second timeout built into Riak's List Keys and List Buckets operations, in earlier versions of Riak (1.2 and below, at the very least).

I'm using 1.4.8.
I can actually dump most keys using curl (sometimes it omits some keys, and sometimes it hangs, but it mostly works). If I query keys using range queries (I am using leveldb), then I can always get all keys (or at least get a consistent answer :) ).
