Hello together,

i have a problem writing a JSON-struct to a file. I use a standard "file node" to write the data into a JSON-File. But after some (20 to 40) good cases, the file is corrupt. It looks like this:

{"payload":{"OperatingTime\_Sec":343.282,"OilBurnerStarts\_Cnt":2,"OilConsumption\_Liter":0.1804614402777778}}9444444446}}

Is this a known issue?

regards  
Florian

What version of NR are you using? There was such an issue in 0.19.0 and was fixed in one of the later maintenance releases.
