Is there special characters (non ascii) in any of the data that is being passed back? Can you run --list with the plugin on the first one that is erroring?

We use windows with russian language

[AlexSavVl]

The same problem with ncpa 2.1.1 and AIX 6.

From https client all works until I set "Run as a Nagios Ccheck". On both - windows and AIX

[jomann09]

What is the output of the ncpa_listener.log on AIX? We will not be able to fix any issues on NCPA versions that are in the past though, we no longer support AIX 6.

[AlexSavVl]

Ok. Fix on current Windows, please.

Closing this as duplicate of #439 will track it there
