I don’t see this in the log of my SOGo instance.

It’s about the gnustep implementation of the NSRegularExpression.
I think it’s more like a warning for developers. If there’s no issue, I’d ignore it.

SOGo uses gnustep for developing the GUI, see SOGo docs. It aims to be compatible to Apple.
The NS8RegularExpression implementation of gnustep seems to be simpler than the Apple one.

Is it possible to trigger the log entry by searching in SOGo or on DAV clients?

Is there a special device that triggers the log entry?

I’m not having the error anymore in the logs since yesterday.
Strange because nothing has been changed, but i’ll keep monitoring it to find the device causing it
