ONC/RPC buffer overflow?

[potatop]

I'm getting the following error when sending a metric with 10 attributes. How can I increase this buffer?
I tried changing the udp receive buffer in gmond to 20 mb but that did not help.

I encountered the same errors as yours. The problem is the XdrBufferEncodingStream( MAX_BUFFER_SIZE ) use the fixed buffer 2014 size， In my case，one metric maybe more then 15 tag&value, and one tagName is 170byte long . So the I encounter this error.

My current solution is make this buffer size bigger. maybe the gmetric4j project should make this buffersize configurable.
