SERVICEPERFDATA output is only 255 char long on Nagios 3.0.1

[Max]

Hi,

Look at p1.pl in the Nagios directory, if your script is running under
ePN you will need to replace occurances of 256 in that script with
4096 as the script does a substr() and only takes the first 256 chars
of output.  Ran into this myself, meant to submit a patch, would be
really nice for configure to set this based on the settings in the
nagios .h file that sets maximum output length at compile time,
unfortunately I haven't had the time to do the patch yet.
