[Xymon] [External] Re: Windows XymonPSClient v2.37

Wed Feb 20 17:54:52 CET 2019

I left it running overnight to see if the slowscan was the issue, but 
the cycle has passed more than once now.  The current log said it was on 
collection 36 of 72.

I just restarted the service, waited 15 minutes to let things cycle a 
few times, but still no update is occurring.

Here's the last few lines of the xymonclient.log
