PROCS turned purple 🔗 link

I am running Xymon version 4.2.0-1 and I have started to see the PROC column go purple within the past few hours for just two servers.

The last report came from these two servers about 3 hours ago and I've seen nothing since.

Everything else is reporting fine on both those servers, it's just the PROC column that is purple.

Any ideas why this is happening?

Thanks
