I'm using Riak 1.3.1. The bucket in question has the following options enabled:
Sometimes I have about 200 siblings under a single key. If I try to write another sibling, try to merge siblings or try to delete the key I get a "500 Internal Server Error". For example:
<html><head><title>500 Internal Server Error</title></head><body><h1>Internal Server Error</h1>The server encountered an error while processing this request:<br><pre>{error,badarg,

If you want me to provide more details, let me please know what logs or files should I inspect. The logs I checked don't provide more details than this.
This error happens only sometimes, but when it does, it's impossible to delete the object. The only workaround I know is to turn off the search. It's possible to delete the object then, but the corrupted data stay in the index.
