openzwave log rotation (results in Truncated file with nothing in it)

[kman]

Hi,
After 2/3 weeks of continuous running (without rebooting), right after logrotation, the OZW log file ends up being truncated without anything in it, everything carries on as it is - it is just that the log file remains empty.

jfyi - openZwave version being used is - 1.3.492

Do you think there is anything wrong with my logrotation config?

Here is my logrotation config:
/usr/src/domoticz/Config/OZW_Log.txt{
daily
rotate 7
missingok
notifempty
compress
copytruncate
}

Many thanks.
