Data received at port UDP:8125 are sometimes concatenated before being processed

[stayen]

I noticed that statsd at times concatenates data received at UDP:8125 (default port) before processing it. I.e., if I send sequence of data like

example.filesInFolder:1|c
example.listFolderTR:4|ms
example.httpSendTR:8|ms
example.httpSend:1|c

statsd may process single concatenated line

example.filesInFolder:1|cexample.listFolderTR:4|msexample.httpSendTR:8|msexample.httpSend:1|c

instead, creating various bogus databases in storage engine (graphite)

Looks like there's correlation between how many lines are received at UDP:8125 and frequency of the above behavior (the faster data are sent, the more often concatenation happens).

Is it possible to prevent the above from happening?

I wonder if appending a newline to your metrics would fix this.

@bagrounds Looks like it does, at least in certain cases (will do thorough checks anyway). Thanks.

I realise I'm asking you to cast your mind back well over a year, but did this work for you @stayen? With the recent revival of this project I'm wondering if this is still something we should be looking at.
