MAX_PLUGINOUTPUT_LENGTH Buffer Size
Brought to you by:

Maybe you already now the issue.
In a distributed environment (several collectors and a central monitoring server) NSCA submits only 512 byte data.
This is quite bitty with Nagios 3.x and when the plugin output data including the performance data is bigger than that.
For test purposes I set the the variable MAX_PLUGINOUTPUT_LENGTH to 4096 and it worked well.
Maybe you can put that into an offical release?
