Hi Mark,
It’s an error that means there is no function clause in
riak_object:merge_contents that matches the given arguments. It is hard to tell
from the snippet of log you posted what the issue is here since the arguments
are truncated. Is this related to you cluster restore from a backup? It looks
like it is related to your periodic read timeouts.
What version of Riak are you running, and what are the bucket properties for
this object? Is there more information in the error log, any messages about
hd([]) for example?
Can you grab the actual object in questions from each of the primary vnodes and
in some console manually run the merge function and see what the results are?
If you need help with how to do this let me know.
Cheers
Russell
