Hello

It's still problem with max plugin output length in 3.0b6. The increase
of max plugin output length cap from 4kb to 8kb was announce in Changelo=
g.
The maximum of output is defined by these constants in common.h nagios.h

/*
NOTE: Plugin length is artificially capped at 8k to prevent runaway
plugins from returning MBs/GBs of data
back to Nagios. If you increase the 8k cap by modifying this value,
make sure you also increase the value
of MAX_EXTERNAL_COMMAND_LENGTH in common.h to allow for passive
checks results received through the external
command file. EG 10/19/07
*/

#define MAX_PLUGIN_OUTPUT_LENGTH 8192 /* max length of
plugin output (including perf data) */
#define MAX_EXTERNAL_COMMAND_LENGTH 8192 /* max length of
an external command */

But the maximum length of message pushed to nagios through external
command file is limited to 4kb.
You can use this simple bash skript for test this bug.
