Problem with corrupt JSON File

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.

i'am using an older one v0.17.5.
