Strange characters in output when using check_logfiles with 3.0a5

[Peter Ringe]

Hi Ingo,
Hi all,


at least Im sure there  is a problem with the epn concering Plugin-Output.
I remarked this already some month ago for 3.0a1 and looking for other 
guys,
seeing the same problem. ([Nagios-devel] problems epn with 3.0a1 , 
21.03.2007)

In between there have been some more discussion concerning epn that the 
plugin result
is scrambled up Inside the empedded Perl, the plugin  putput is correct, 
but when the output reaches
nagios, the first 4 or 8 byte of Plugin Output seems to be overwritten.

I do not understand embedded perl in detail, but perheaps there is 
someone else, who can
have a look at that problem.

I think it's a real problem for nagios 3.0, because a lot of people use 
epn due to perfomance.
All those guys cannot switch over to nagios 3.0 without epn.



Regards
