Hello!
We use multibackend where each backend is a bitcask backend. A few days
ago riak began to merge and it seems that it got into eternal cycle. Cuz
it's trying to merge unreasonably long:
look
1.2G /var/lib/riak/kv_bitcask/exp_2month
69M /var/lib/riak/kv_bitcask/exp_1day
And these to backends are being merged already for 1 day!!! It seems
that riak stuck. What can we do?
