Hi,

We've seen this happen a couple of times before. We haven't been able to identify a likely suspect yet. What we think is happening is that a non-Accumulo process happens to connect to an Accumulo process, send a message that isn't a Thrift message (that Accumulo uses internally) and it happens to try to allocate an extremely large buffer.

https://issues.apache.org/jira/browse/ACCUMULO-2360

We introduced an upper limit on the size of an RPC message and this is what this error message is telling you. Are you saying that this is still causing the Master process to crash? If so, are there any error messages at the end of the .log, .out or .err files?
