I'm going to guess that you're using nagios-2?

[nagios-2-src/include]$ grep MAX_PLUGIN *

objects.h:#define MAX_PLUGINOUTPUT_LENGTH			348	/* max. length of  
plugin output */

I expect that you can probably increase the value above within  
reasonable limits (say 1024 or less) and recompile with no detriment  
but YMMV.

According to What's New for nagios-3, this has been increased to 4K  
along with support for multi-line plugin output.
